Mayon Volcano remains quiet on Monday despite Sunday’s phreatic eruption that spewed white ash from the volcano, the country’s chief volcanologist said.
Dr. Teresito Bacolcol, director of the Philippine Institute of Volcanology and Seismology, said the agency has not registered any volcanic earthquake from Mayon for the past 4 days.
“Maganda po ‘yun. Ibig sabihin, walang magma na umaangat. ‘Yung phreatic eruption nasa bunganga lang po ‘yan, meron kang hot material, coming into contact with water. As a result, nagkakaroon ng steaming, nagkaroon ng sudden burst and not as violent as magmatic eruption but can still send ash and rock hanging,” Bacolcol said in a TeleRadyo Serbisyo interview.
He added Phivolcs has yet to reports of volcanic ash reaching villages near the volcano. “Hindi babaguhin ‘yung alert level [for] now,” he said.
Phivolcs earlier reported that a phreatic eruption from the Mayon Volcano summit occurred at 4:40 p.m. Sunday and lasted four minutes and nine seconds, based on the seismic record.
“The event generated a booming sound, rockfall, pyroclastic density currents or PDC and a 1,200 meter-tall plume that drifted to the southwest,” the agency added.
