ACT Alert: Mayon volcano, Philippines
For more than two weeks, Mayon Volcano has continued to emit lava. The lava emission has already gone beyond the boundary of the 6-kilometer radius of the permanent danger zone. In its August 14, press release, the Philippine Institute of Volcanology and Seismology-Bicol (PHIVOLCS) said that Mayon's seismic activity is now entering its most dangerous phase after weeks of ejecting lava and ash. The burst of pyroclastic flow marked the first time Mayon shot out fast-moving hot gas and rock fragments. Pyroclastic flows, locally known as "oson," are hazardous and often fatal. They travel with high velocity and could destroy everything on their path. Blistering gas and volcanic debris could travel at speeds of at least 60 kilometers per hour.
