Last week, Volcan de Fuego, which is Spanish for Fire Volcano, began a new eruptive phase just months after the previous eruption in June killed at least 165 people - with 260 more declared still missing in August 9. Guatemala City-Guatemalan authorities declared a red alert and evacuated around 4,000 people at the start of the week. On Wednesday, the volcano still averaged seven to ten explosive eruptions per hour, which generated shock waves that vibrated structures within 20 km. According to the Smithsonian Institute, "ash plumes from the explosions rose 1300m above the cone in the summit crater" reaching several areas, including Panimache, Morelia, El Provenir and Santa Sofia. Incandescent material was also ejected 150m high, causing avalanches, some that traveled long distances in the Las Lajas, Ceniza, and Seca. Guatemala is consistently under threat from Fuego, which has erupted a total of five times in 2018. The previous ones happened in February and June - with the one taking place on June 3 at noon local time leading to devastating consequences. The unexpected event and its force left little time for people to evacuate. The central American country lies on the Pacific Ring of Fire - an arc of tectonic instability caused by the earth's converging plates. Earthquakes, tsunamis and volcanic eruptions are therefore particularly common in these regions. Ben van der Pluijm, a geologist at the University of Michigan, told Express.co.uk: "On a yearly basis we have roughly 1500 magnitude 5-5.9 earthquakes around the world.
