Volcano Eruption in Mexico on October 01 2016 05:09 AM (UTC).
Activity at the volcano continues but its intensity has decreased over the past week. Lava effusion into the viscous lava flow on the southern side continues (if at all) at very low rate, manifesting itself by occasional rockfalls from the thick lava flow front. Explosions of small to moderate size at the summit vent are relatively frequent, probably destroying the recently emplaced dome. Members of Colima University recently sampled the lava flow in order to investigate its chemical properties which might give a clue to explain the recent effusive phase of the volcano which came very suddenly and was very fast. In particular, it would be interesting to see if the new lava is different from the lavas of July last year or if it also is relatively rich in dissolved water (that help explain the fast rise of the magma column).
The effusion of the viscous lava dome spilling over the southwestern rim as a broad lava flow continues at the volcano. After a peak of activity around 1-2 Oct, the rate of effusion dropped 4 Oct, but regained again strength since 6 Oct and has been intense since. The lava dome's top slowly becomes more and more visible from below, although it currently only overspills the crater on the SW side feeding the lava flow. The latter is currently about 2000 m long and 270 meters wide at its front at the base of the cone.
Some 300 villagers were evacuated to a nearby shelter prior to the Colima Volcano erupting in western Mexico, Chief Operating Officer of the State System of Civil Protection Melchor Ursua Quiroz said Saturday. "Temporary accommodations, which allow us to relocate approximately 300 people from the communities of La Becerrera, La Yerbabuena and San Antonio in the municipality of Comala and other villages, have already been opened," Quiroz said, as quoted by the newspaper Informador. The activity of the Colima Volcano increased late on Friday, leading to the release of a large amount of magma, he added. The Colima volcano, located in western Mexico between the states of Colima and Jalisco, is one of the most active volcanos in the country with more than 40 eruptions recorded since 1576.
