MANILA —\u00a0Hazardous eruption is possible in Mayon Volcano, which continues manifesting unrest.<\/p>\n

“Such eruption may occur there within the forthcoming days or weeks,” said Philippine Institute of Volcanology and Seismology (Phivolcs) volcanologist Paul Alanis.<\/p>\n

Alanis noted that the continuing flow of magma or molten rock from Mayon’s crater and occurrence of earthquakes in the volcano are indicating the possibility of a hazardous eruption there.<\/p>\n

Mayon’s eruption is considered hazardous if this event can generate pyroclastic flow, said Alanis.<\/p>\n

Pyroclastic flow occurs when the cocktail of hot gases and materials a volcano spews during its explosion cascades along this mountain’s slopes, he noted.<\/p>\n

Alanis warned pyroclastic flows are fast-moving and already killed people in the past.<\/p>\n

Magma from previous Mayon eruptions is what is flowing out of this volcano’s crater at present, Alanis added.<\/p>\n

New magma beneath Mayon is pushing up the old magma, so such outflows are occurring, he said, adding that volcanic earthquakes in Mayon also indicate that magma is rising there.<\/p>\n

He warned Mayon would eventually spew the new magma if old magma no longer blocks the volcano’s vent.<\/p>\n

Alanis said Phivolcs on Sunday night (January 14) raised Mayon’s alert level from 2 to 3 due to relatively high unrest in this volcano.<\/p>\n

He reiterated Phivolcs’ call for people to avoid entering Mayon’s danger zone, particularly amid such unrest.<\/p>\n

Mayon already erupted anew this week, when magma commenced flowing out of the volcano’s crater as lava, he said.<\/p>\n

Lava flows aren’t hazardous, since they cascade slowly, he noted.<\/p>\n

Pyroclastic flows can cascade at about 100 kilometers per hour, so people can’t outrun these, he said.<\/p>\n

“No one can escape pyroclastic flows,” he warned earlier.<\/p>\n

Mayon is among the country’s active volcanoes.<\/p>\n

Active volcanoes are those that erupted within the last 600 years as shown in the documentation of these events, said Phivolcs.<\/p>\n

Phivolcs added active volcanoes can be those that erupted within the last 10,000 years, based on analyses of datable materials.<\/p>\n
