On Saturday, July 1, State volcanologists reported 'increased' eruptive activity at the restive volcano due to the collapse of a lava dome on Mayon Volcano and more frequent volcanic earthquakes. | ManilaBulletin READ:
The largest of the pyroclastic density current activities was detected on June 30 at 1:01 p.m. and lasted eight minutes, while four visible three- to four-kilometer long PDCs lasting about four minutes each were observed between 6 p.m. and 8 p.m.
The generation of more pyroclastic density currents as a result of the collapse of a lava dome on Mayon Volcano, as well as the occurrence of more frequent volcanic earthquakes, characterized the “increased” eruptive activity at the restive volcano on Friday, June 30, said State volcanologists on Saturday, July 1.
It added that PDCs cascaded down the Basud Gully on the eastern slope of Mayon Volcano on Friday, producing one-kilometer-high ash clouds. Phivolcs also noted that the concentrations of sulfur dioxide started to increase on June 29 and were averaging 1,002 tons per day when they were last measured on June 30.Mayon Volcano is still under Alert Level 3 as it is “currently in a relatively high level of unrest as magma is at the crater and hazardous eruption within weeks or even days is possible.”
