Volcano Eruption in Philippines on January 13 2018 12:14 PM (UTC).
Renewed activity was recorded on Mayon Volcano on Thursday, authorities said, nearly three weeks after the alert level was lowered due to decreased chances of a hazardous eruption. There was a "lava collapse" in the volcano, which caused ash, rocks and gases to flow out, Philippine Institute of Volcanology and Seismology Director Renato Solidum told ABS-CBN News. There was "no eruption," Solidum said, adding that the alert remained at 3, the midpoint of a five-step warning system. Before the alert was lowered in early March, Level 4, the second highest, was in place since January, requiring the evacuation of thousands. Phivolcs will observe the volcano's activity for "several days" and if it shows no more swelling or lava release, it might lower the alert level another notch to 2, Solidum told DZMM radio.
Mayon volcano has continued to spew red-hot lava and clouds of ash into the air after it exploded seven times in just 24 hours as residents report the sound of rumbling from the towering crater for miles. But the Philippines most active volcano shows no signs of letting up as officials revealed lava continued to flow from 7.19am on Thursday to 6am (local time) today erupting on seven separate periods during the timeframe. The Mayon volcano, which stands at 8,077 foot tall, is one of the most active in the Philippines and has continued to erupt for weeks. The Philippine Institute of Volcanology and Seismology reported: "It generated ash plumes that rose 300 metres above the summit crater before drifting southwest. These were accompanied by rumbling sounds audible beyond 10 kilometres of the summit crater. "At night, lava flows were observed to continue moving downslope within 3.3 kilometres, 4.5 kilometres and 1.9 kilometres from the crater on the Miisi, Bonga and Basud Gullies, respectively." The alert level for Mayon has recently been downgraded to three on a scale of five. Authorities said although the threat of further "hazardous explosive eruptions" is unlikely, locals and visitors must prepare for "unrest to continue". The Philippines sits on the "Ring of Fire" a large area in the basin of the Pacific Ocean where volcanic eruptions and earthquakes are frequent. Mount Mayon's last eruption took place in 2013 when four climbers and their guide died after trekking near the summit. Most recent activity has forced nearly 70,000 people to evacuate from areas close to Mount Mayon to escape the threat of eruption. The tens of thousands of people have been forced to flee their homes after a thick grey cloud coated villages in affected areas following two weeks of eruptions. Around 75,550 people have been evacuated to overcrowded relief camps as authorities warn residents far from the area to stay indoors to avoid heavy ash fall.
On 13 January 2018 at 4:21 PM, Mayon Volcano generated a phreatic eruption (steam-driven) that propelled a grayish steam and ash plume approximately 2500 m high that was drifted to the southwest. Based on seismic records the activity lasted approximately 1 hour and 47 minutes. Since 1:00 PM of January 22, 2018 to present, alert status is raised to level 4 (hazardous eruption imminent) by DOST-PHIVOLCS, due to the volcano's phreatomagmatic eruption (increased seismic unrest, lava fountaining and summit explosion).
Mayon's activity in the past 24 hours was characterized by sporadic and lava fountaining, lava flow and degassing from the summit crater. Between 7:34 AM yesterday and 4:06 AM this morning, the seismic network recorded eighty (80) discrete seismic events associated with otherwise obscured lava fountaining that lasted two (2) to forty-nine (49) minutes and were accompanied by rumbling and chugging sounds audible beyond 10 kilometers of the summit crater. Incandescent lava fountains with heights of 100 to 600 meters generated dirty white to gray ash plumes that rose 100 to 800 meters from the summit before drifting west-southwest to southwest. Seven (7) episodes of lava-collapse pyroclastic density current (PDC) events were visually observed between 1:44 PM and 3:05 PM yesterday depositing along Mi-isi. Basud and Bonga-Buyuan Gullies within two kilometers of the summit crater. Lava flow sustained at 3.3 kilometers. 4.5 kilometers and 900 meters on the Mi-isi, Bonga and Basud Gullies, respectively, from the summit crater. Pyroclastic density currents or PDCs remained confined within the farthest recorded reaches of 4.6. 5.2 and 4.2 kilometers on the Mi-isi, Bonga and Basud Gullies, respectively. A total of one hundred forty-three (143) volcanic earthquakes, corresponding to recharge of magma beneath the edifice and lava fountaining events, were recorded by Mayon's seismic monitoring network. Sulfur dioxide (S02) emission was measured at an average of 4,273 tonnes/day on 21 February 2018. Electronic tilt and continuous GPS still record sustained swelling or inflation of the edifice since November and October 2017, consistent with pressurization by magmatic intrusion.
The number of people displaced by an erupting Philippine volcano soared to more than 61,000 by Wednesday (24/01), the country's disaster agency said, as Mount Mayon ejected lava that produced an ash plume 5 kilometers high. The alert remains just one notch below the highest level of 5 after five more episodes of "intense but sporadic lava fountaining" from the summit crater over a 19-hour period from Tuesday morning, state volcanologists said. Lava fountains 500-600 meters high lasted between seven minutes and more than an hour and generated ash plumes 3-5 km above the crater, the Philippine Institute of Volcanology and Seismology (Phivolcs) said. Schools were shut in 17 cities and municipalities in Albay and nearby Camarines Sur Province, which was also affected by ashfall. Some 56 flights were canceled because of Mayon, the Philippines' most active and most picturesque volcano. There were 55,068 residents in temporary shelters, a substantial increase from about 40,000 on Monday. Some 6,165 evacuees were staying elsewhere. The number of displaced increased after the provincial government expanded the danger zone around the 2,462-meter volcano to a radius of 9 km from the Phivolcs-recommended 8 km no-go zone. Mayon's sporadic eruption, which began on Jan. 13, has affected 54 villages in Albay, with a combined population of 71,373 people.
Nearly 15,000 people have fled from villages around the Philippines' most active volcano as lava flowed down its crater Monday in a gentle eruption that scientists warned could turn explosive. The Philippine Institute of Volcanology and Seismology increased the alert level for Mount Mayon late Sunday to three on a scale of five, indicating an increased prospect of a hazardous eruption "within weeks or even days." Lava flowed at least half a kilometer (less than half a mile) down a gulley from the crater on Monday morning and ash clouds appeared mid-slope as lava fragments rolled down, said Renato Solidum, who heads the volcano institute. It was hard to track down the lava flow given the thick clouds shrouding the volcano. Molten rocks and lava at Mayon's crater lit the night sky Sunday in a reddish-orange glow despite the thick cloud cover, leaving spectators awed but sending thousands of residents into evacuation shelters. Disaster-response officials said more than 14,700 people have been moved from high-risk areas in three cities and four towns in an ongoing evacuation. People in the danger area have put up huge white crosses in the past in their neighborhoods, hoping to protect their lives and homes. "There are some who still resist but if we reach alert level four, we'll really be obligated to resort to forced evacuation," Cedric Daep, an Albay emergency official, told The Associated Press. Level four signifies the volcano could erupt violently within days. Mayon lies in coconut-growing Albay province about 340 kilometers (210 miles) southeast of Manila. Three steam-explosions since Saturday have spewed ash into nearby villages and may have breached solidified lava plugging the crater and caused lava to start gushing out, Solidum said. With its near-perfect cone, Mayon is popular with climbers and tourists but has erupted about 50 times in the last 500 years, sometimes violently. In 2013, an ash eruption killed five climbers, including three Germans, who had ventured near the summit despite warnings of possible danger. Experts fear a major eruption could trigger pyroclastic flows - superheated gas and volcanic debris that race down the slopes at high speeds, incinerating or vaporizing everything in their path. More extensive explosions of ash could drift toward nearby towns and cities, including Legazpi city, the provincial capital, about nine miles (15 kilometers) away. The bulletin sent Sunday night said a hazardous eruption was possible within weeks or even days. It said the glow in the crater signified the growth of a new lava dome and that the evacuation zone should be enforced due to the dangers of falling rocks, landslides or a collapse of the dome. Airplanes have been warned not to fly close to the volcano. Mayon's first recorded eruption was in 1616. The most destructive in 1814 killed 1,200 people and buried the town of Cagsawa in volcanic mud. The belfry of a Cagsawa church juts out of the ground in a reminder of Mayon's deadly fury and has become a tourist attraction.
The lava in one of the channels on Mount Mayon has advanced 300 meters more since Friday according to the latest bulletin of the Philippine Institute of Volcanology and Seismology (Phivolcs) released on Sunday at 8 a.m. According to Phivolcs's latest 24-hour observation of Mayon's state of unrest, from four kilometers Friday, the lava has flowed to 4.3 kilometers on the Bonga-Buyuan Gully towards Legazpi City. The lava flow on the Miisi Gully towards Daraga town, on the other hand, has reached 3.2 kilometers. Mariton Bornas, chief of Phivolcs' Volcano Monitoring and Eruption Prediction division, said that it was still hard to tell if the lava would reach up to six kilometers just like it did in December 29, 2009. "It is hard to say because the lava could also split and branch out to other channels," Bornas told Inquirer. Bornas also said that in their calculations, the average outflow of lava per day is at 2 million cubic meters. According to Phivolcs, during the last 24-hour monitoring of Mayon, the volcano emitted another ash column that reached 500 meters high and one weak lava fountaining event that lasted for a little more than half a minute. Also, 55 volcanic quakes and nine rockfall events were recorded. According to Cedric Daep, chief of Albay Public Safety and Emergency Management Office, the village center nearest to the gully is about seven to eight kilometers away. Alert Level 4 is still raised over Mayon and Phivolcs maintains that residents must stay away from the 8-kilometer danger zone.
Lava flowing out a Philippine volcano has spread up to 3.6 kilometers (2.2 miles) since it began intense eruptions more than two weeks ago. Streaks of red glowed atop the summit of Mount Mayon during a mild eruption Thursday morning as the moon set, hours after a blue moon and supermoon coincided with a lunar eclipse. The Philippine Institute of Volcanology and Seismology said lava fountains and emissions of gas and ash have been sporadic. The eruptions fed lava flows in two areas that already exceed 3 kilometers (1.8 miles). The danger zone around Mayon extends 8 kilometers (5 miles), though authorities have struggled to keep villagers from returning to check on their homes and farms and tourists from trying to photograph the volcano's dramatic displays. Mayon in northeastern Albay province has been erupting for more than two weeks, forcing more than 84,000 villagers to flee to crowded emergency shelters. Scientists fear a more violent eruption could be imminent.
State volcanologists detected three eruption episodes overnight as restive Mayon Volcano continued its heightened activity. In a report on Super Radyo dzBB on Sunday morning, Philippine Institute of Volcanology and Seismology (PHIVOLCS) Director Renato Solidum Jr. was quoted as saying that the eruption episodes were recorded beginning early Saturday evening and until early Sunday morning. PHIVOLCS data showed that the lava fountaining events were detected at 6:22 p.m. Saturday; 12:45 a.m. and 5:36 a.m. Sunday. Due to thick clouds from bad weather condition around Mayon, the actual lava fountaining events were not seen but PHIVOLCS instruments have recorded the episodes. While Mayon had fallen silent for 27 hours before the series of lava fountaining starting early Saturday evening, Solidum said that the temporary silence doesn't mean that restive Mayon is losing steam, but possibly it has changed its eruption style. PHIVOLCS' lahar advisory was still up even as the agency advised residents to be vigilant, especially those living near river channels around the volcano. It said that some nine million cubic meters of pyroclastic material deposits are in the Buyuan and Miisi watershed areas; and another 1.5 million cubic meters in the western side of Mayon. Solidum expressed fears that a heavy lahar flow might occur anytime as heavy rains have continued around the volcano.
Mayon Volcano threw up a gigantic ash column early Friday evening in another day of intense volcanic activity. From Legazpi Bay in Albay, residents and tourists watched restive Mayon Volcano doing a pyroclastic show at sundown. Earlier, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said that pyroclastic flow was intense but sporadic over a span of 24 hours from late Thursday to early Friday. It said that rising plumes went up to 4.8 kilometers high. As of Friday, the number of evacuees rose to 80,000, a report on Super Radyo dzBB said on Saturday morning. However, the eruption has prompted a significant increase in tourist arrivals, the report added. A search on previous Mayon eruptions shows that in 2014, at least 63,000 people were evacuated from Albay volcano's wrath. In 2006 some 30,000 fled their homes, and the 1993 eruption left 70 people dead.
Philippine Institute of Volcanology and Seismology (PHIVOLCS) shared the video of the eruption which shows lava begin to pour down the slope before a ash cloud was released. The video was filmed at 6.11am local time yesterday from a volcano observatory in Legazpi City, Albay, in the eastern Philippines. Hot red lava spewed out of the crater six times between 6.02am local time on Wednesday and 3am local time on today, according to PHIVOLCS. The lava fountains reached 400m to 500m high, ash plumes soared up to 5km above the crater, 13 tremors were recorded and there were "numerous rockfall events". A huge plume of ash billowed from the glowing peak of the Philippines' most active volcano again and magma continued to move below the ground today. But nevertheless there were serene scenes today in Legazpi City were families were seen gathered today while looking out towards the erupting volcano. A young child was pictured looking worried as the woman holding him watched the volcano, while another villager leaned out of a tuk tuk to get a better view. Mayon's unrest has displaced about 75,500 people, the majority of whom are in evacuation centres, where children lined up for meals and parents braced for the possibility of a long stay away from home.
Authorities in the Philippines are warning people to stay clear of the volatile Mount Mayon volcano after multiple eruptions spread lava and ash for kilometers. A thick column of ash streamed five kilometers into the air above the volcano, in Albay province in southeastern Luzon, and spread over neighboring districts, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said in a statement Tuesday. Falling ash left Guinobatan, a town of around 80,000 people, in a state of "zero visibility," according to affiliate CNN Philippines. PHIVOLCS said it had also detected "two explosion-type earthquakes" as well as dozens of rockfalls and "lava fountaining episodes" in and around the crater on Monday. The alert level for Mayon volcano - the country's most active volcano - was raised to four from three last week after it exhibited increasing seismic unrest and summit explosions. The highest level - five - means a hazardous eruption is underway. More than 56,000 people fled the surrounding areas and were taking shelter in evacuation camps, officials told the AP; the army and police were helping others move from their homes. Lava has been flowing down from the crater since last week.
The Philippines' most active volcano exploded thunderously Monday, sending a huge gray column of lava fragments, ash and steam into the sky and prompting authorities to warn that a violent eruption may be imminent. The noontime explosion sent superheated lava, molten rocks and steam cascading down Mount Mayon's slopes and shrouded nearby villages in darkness, said Renato Solidum of the Philippine Institute of Seismology and Volcanology and other officials. Authorities raised the alert level to four on a scale of five, which means an explosive eruption is possible within hours or days. A danger zone around Mayon was expanded to 8 kilometers (5 miles) from the crater. "If the eruption is vertical, it's possible pyroclastic flows or pyroclastic density currents may cascade down in all directions," Solidum told a news conference, warning villagers and tourists not to venture into the no-go zones and airplanes to stay safely away from the crater and ash-laden winds. More than 27,000 villagers have fled since Mayon started acting up more than a week ago. Mayon is in coconut-growing Albay province, about 340 kilometers (210 miles) southeast of Manila. With its near-perfect cone, it is popular with climbers and tourists but has erupted about 50 times in the last 500 years, sometimes violently. In 2013, an ash eruption killed five climbers who had ventured near the summit despite warnings. Mayon's first recorded eruption was in 1616 and the most destructive, in 1814, killed 1,200 people and buried the town of Cagsawa in volcanic mud. The Philippines lies in the so-called "Ring of Fire," a line of seismic faults surrounding the Pacific Ocean where earthquakes and volcanic activity are common. In 1991, Mount Pinatubo in the northern Philippines exploded in one of the biggest volcanic eruptions of the 20th century, killing about 800 people.
The Mayon Volcano shot what appeared to be a huge ash column on Monday, the second in over a week and as authorities braced for a possible "hazardous eruption." Some 27,000 people have been evacuated around the volcano that is renowned for its perfect cone. The alert level was raised to level 4, one notch below the highest warning. This indicates a "vulcanian eruption" is ongoing. Alert level 3 was raised over the volcano on Jan. 14. It is the third highest in a five-step warning system. Mayon draws thousands of tourists, even during minor eruptions, rises 2,460 metres (8,070 feet) above a largely agricultural region some 330 kilometres southwest of Manila. It is considered the nation's most active volcano. Steam-driven eruptions and rockfalls began earlier this month, and the crater began glowing soon after, in what Phivolcs said was a sign of the growth of a new lava dome.
More than 11,000 evacuees have been allowed to return to their homes after they were found to be living beyond the six-to-seven kilometer danger zone threatened by restive Mayon Volcano in Albay province in the Bicol Region, an official reported on Friday. Meladee Azur, the head of the City Disaster Risk Reduction and Management Council (CDRRMC), said the evacuees who decamped, came from several "barangay: (villages) in Albay's capital city of Legaspi, who sought refuge in public school buildings. Azur pointed out the evacuees, representing about 6,000 families, were found to be living from eight to 8.6 kilometers beyond the volcano's expanded danger zone of from six to seven kilometers. "That was a voluntary evacuation. It was not a mandatory evacuation. We just recommended the villagers to evacuate because they couldn't sleep at night," Azur explained. In its latest bulletin on Friday morning, the Philippine Institute of Volcanology and Seismology (Phivolcs) said it allowed the evacuees to decamp after finding that Mayon has not shown signs of an "explosive eruption" despite its current activity of lava flows, tremors and ground deformations. Phivolcs also retained its Alert Level 3 over the volcano with a warning that a major eruption could occur within days or even weeks. Meanwhile, provincial officials said close to 6,000 families or more than 27,000 individuals remained in the evacuation centers in the cities of Tabaco and Ligao as well as the towns of Daraga, Camalig, Guinobatan, Malilipot and Santo Domingo. Mayflor Marie Jumamil, the Department of Education regional spokesman in Bicol, reported that 34 public schools are now being used as evacuation centers in Albay. Close to 9,000 were affected by the suspension of classes due to Mayon's activity amid a warning from education officials that the scheduled graduation of many of the students in March would be affected. On Thursday, Phivolcs said that Mayon, a major tourist attraction in Albay as the volcano with the world's most perfect cone, underwent a "facelift" with a new dome that formed after a recent unrest that started on Jan.13. The dome replaced the old lava dome that was formed when the volcano erupted in 2014, according to Phivolcs.
More than 38,000 individuals have evacuated as lava continued to flow from the Mayon Volcano. Citing the latest report from the Albay Philippine National Police (PNP), Radyo Inquirer 990 AM reported that as of 3 a.m. Thursday, a total of 9,492 families from 39 barangays, 3 cities, and 5 towns have fled their homes under threat from an eruption of Mayon. Chief Inspector Arthur Gomez, Albay PNP spokesperson, said they were prepared to respond to any incident, the report said. Police have been deployed to the towns of Guinobatan, Camalig, Malilipot, Daraga, Ligao City, Tabaco City, and to Legazpi City. On Tuesday, Albay was placed under a state of calamity due to the threat of an eruption.
Mount Mayon, the most active volcano in the Philippines, continued to erupt on Tuesday forcing nearly 35,000 people to evacuate. While the recent eruptions have been relatively weak, scientists warn that they could turn explosive at any time, according to the Associated Press. A thick ash cloud around the volcano has made monitoring its eruptions difficult and also caused ash to settle on nearby villages. Lava flows on Tuesday also forced police to set up checkpoints to keep tourists a safe distance from the volcano. While currently at a level three warning, an upgrade to level four would result in forced evacuations across a larger impact area. In an attempt to keep local villagers from returning to their homes to check on farm animals, officials have planned to set up evacuation areas for animals, including water buffaloes, cows, pigs and poultry, according to Office of Civil Defense regional director Claudio Yucot. Despite being a popular tourist attraction, Mount Mayon has erupted around 50 times in the past 500 years. An eruption in 1814 killed 1,200 people and buried an entire town in a volcanic mudflow. A larger scale eruption could result in more widespread evacuations and travel disruption as the volcano sits less than 16 km (10 miles) from Legazpi City, the capital of Albay province. Daily showers and localized downpours are expected across the area through at least Thursday. Any downpours will heighten the risk for flooding and mudflows around the volcano.
The Philippine Institute of Volcanology and Seismology (Phivolcs) raised Mayon Volcano's alert status to Alert Level 3 Sunday evening, as 141 rockfalls have been recorded in the past 24 hours. Phivolcs resident volcanologist Ed Laguerta said this means that magma is at the crater and that hazardous eruption is possible within weeks or days. "The six-km radius Permanent Danger Zone (PDZ) around the volcano and the 7-km Extended Danger Zone (EDZ) on the southeastern flank enforced due to the danger of rock falls, landslides and the 3 km lava flows," he said. Laguerta said the agency seismic network recorded two volcanic earthquakes and 141 rockfall events during the past 24 hours. Degassing at the active vents could not be observed due to thick clouds covering the summit. He added that crater glow was visible early Monday morning, although rain clouds prevented visual observation of the crater during the day. Mayon's summit crater is now exhibiting bright crater glow that signifies the growth of a new lava dome and beginnings of lava flow towards the southern slopes. "Based on records, Precise leveling data obtained on November 7 to 11, 2017 indicated slight inflation of the edifice relative to September 2017. This is also exhibited in increased rates in the inflationary trends recorded by continuous GPS and tilt since October and November 2017, respectively. Sulfur dioxide (SO2) emission was measured at an average of 856 tonnes/day on 03 December 2017," Laguerta said. Alert Level 3 remains in effect over Mayon Volcano, which means that it is currently in a relatively high level of unrest. Albay Public Safety Emergency Management Office (APSEMO) head Cedric Daep said, the public is strongly advised to be vigilant and desist from entering the six (6) kilometer-radius Permanent Danger Zone (PDZ) and the 7-km Extended Danger Zone (EDZ) on the southern flanks, due to the danger of rockfalls, landslides and sudden explosions or dome collapse that may generate hazardous volcanic flows. Increased vigilance against pyroclastic density currents, lahars and sediment-laden streamflows along channels draining the edifice is also advised. The PDRRMC, Albay Provincial Safety and Emergency Management Office, and the mayors of the affected cities and municipalities will have an emergency meeting at 1:00 p.m. Monday.
The Philippine Institute of Volcanology and Seismology (Phivolcs) raised Mayon Volcano's alert status to Alert Level 3 - which means it has an increased tendency towards eruption - at 8 p.m. Sunday, less than 24 hours after Alert Level 2 (increasing unrest) was raised here. Ed Laguerta, Phivolcs Bicol chief, said that they were still unable to determine the distance of the lava flow because of the clouds. But the brighter crater glow is an indication of lava. "The brighter glow of the crater is an indication of the initiation of lava flow on the southern slope of the volcano," Laguerta told Inquirer. "We cannot determine the distance yet because of the thick clouds." Laguerta said that because of the raising of the alert status, the danger zone is now extended to the 7-kilometer radius of the volcano. In Camalig, Rommel Negrete, Municipal Disaster Risk Reduction and Management officer, said that as of press time, they were undergoing evacuation of residents in Barangay Quirangay and parts of Barangay Sua. "There are already108 families from Quirangay, but it is expected to rise to 200," Negrete said. He said that the evacuees would brought to Camalig North Central School where they would stay until the alert status is lowered. Local government trucks were used to evacuate the residents. Negrete also said that they had run out of face masks by Sunday afternoon. Residents were advised to use clean, damp cloths as alternatives to avoid the negative effects of ash fall events. In Tabaco, Hugo Buen, the city's DRRM officer, said that they were also evacuating residents in Barangays Comon, Nagsipit, Magapo, Buhian, Oson, and Buang. The residents would be brought to the nearest schools for shelter. In Guinobatan, Egmidio Pavericio, Jr. said that there were only few residents within the 7-kilometer radius, but they were still undergoing evacuation in Barangay Muladbucad Grande. As of 4:21 p.m. of Saturday, Phivolcs was able to record 158 rockfall events in affected areas. It was also able to record three phreatic eruptions since Saturday.
More than 5,000 people in 3 municipalities of Albay fled their homes due to the restive Mayon Volcano on Sunday, January 14. Two more phreatic or steam-driven eruptions were recorded on Sunday - one at 8:49 am and another at noon. According to the Albay Public Safety and Emergency Management Office (APSEMO), 1,547 families or 5,857 persons evacuated from Camalig, Guinobatan, and Malilipot. The evacuation had begun on Saturday evening, January 13, due to the ash eruption at 4:21 pm that day. The APSEMO had ordered the evacuation of residents inside the 6-kilometer (km) permanent danger zone (PDZ). The 6-km PDZ includes the barangays of Quirangay, Sua, Tumpa, and Tinubran in Camalig; Tandarora and Maninila in Guinobatan; Miisi, Budiao, and Matnog in Daraga; Calbayog and Canaway in Malilipot; Buang, Buhian, and Magapo in Tabaco City; and Baligang and Amtic in Ligao City. Residents outside the 6-km PDZ who are experiencing ashfall should also take precautionary measures. "Please wear [a] protective dust mask or wet, damp cloth to cover your nose and mouth," Albay Governor Al Francis Bichara said. Bichara also suspended preschool to senior high school classes for Monday, January 15, in all public and private schools covered by the evacuation order. "Suspension of classes will take effect tomorrow (Monday) until lifted in all public and private schools situated in identified barangays where classrooms are being used by Mayon evacuees in order to give these schools ample time to organize [a] special scheme of classes," he said. The Bicol Regional Training and Teaching Hospital (BRTTH) also went on white alert following the raising of the Mayon Volcano alert from Level 1 to Level 2. Dr Eric Raborar said the hospital's emergency department is on standby for possible cases related to the ash eruptions. Meanwhile, the Philippine Institute of Volcanology and Seismology (Phivolcs) advised civil aviation authorities to tell pilots "to avoid flying close to the volcano's summit as ash from any sudden eruption can be hazardous to aircraft." "Based on the seasonal wind pattern, ashfall events may most likely occur on the southwest side of the volcano," added Phivolcs.
Saturday's eruption was followed by rumbling sounds and a faint glow in the crater, according to the Philippine Institute of Volcanology and Seismology. The Philippines raised the alert for the Mayon volcano early Sunday, citing signs of rising magma. The level of danger was etched-up a notch following concerns that the phreatic or steam-driven eruptions could lead to hazardous emissions. "The public is strongly advised to be vigilant and desist from entering the six-kilometer radius Permanent Danger Zone to minimize risks from sudden explosions, rockfall and landslides," Philippine Institute of Volcanology and Seismology (Phivolcs) warned. Phivolcs said the first "steam-driven eruption" started at about 5:00 p.m. local time, recording an ash column of 2500m high. The Level 2 alert suggests that the current activity is "probably of magmatic origin, which could lead to more phreatic eruptions or eventually to hazardous magmatic eruptions." A phreatic eruption occurs when magma heats ground or surface water, resulting in steam rising into the sky. Saturday's eruption unleashed ash, rocks and sulfuric odor, and was followed by rumbling sounds and a faint glow in the crater, according to Phivolcs. "The public is strongly advised to be vigilant and desist from entering the 6k-radius Permanent Danger Zone to minimise risks from sudden explosions, rockfall and landslides," Phivolcs said. A second ash eruption was also recorded before noon on Sunday. "We have not reached the critical level," head of the Albay Provincial Disaster Risk Reduction and Management Office, Cedric Daep, insists in a radio interview. "Alert level 3 is what we considered critical, 4 is when eruption is imminent, and 5 is eruption in progress," he said, adding that people in evacuation centers may be allowed to return homes if Phivolcs does not raise the level. Phivolcs chief Renato Solidum said the volcano appeared due for another eruption. Residents were evacuated from two villages near the volcano on Saturday. The institute advised people near ashfall to cover their noses and mouths with a damp, clean cloth or dust mask. Mayon's most destructive eruption was in February 1841, when lava flows buried a town and killed 1,200 people. It last erupted in 2014, spewing lava and forcing thousands of people to evacuate. The volcano has been displaying abnormal behavior since late last year.
