Philippines’ Mayon Volcano “Quietly Erupts”, PHIVOLCS Alerts
According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the tropical depression will bring heavy rainfall from Sunday, triggering floods and landslides.
An official statement from the Philippine Institute of Volcanology and Seismology "strongly recommended" that residents at the foot of the cone-shaped Mayon volcano in Albay province, approximately 500 km southeast of Manila, "be vigilant and ready."
The institute also stated that the prolonged heavy rainfall could trigger lahar flows of ash and volcanic debris spewed by the volcano, which started erupting on June 8.
"The Mayon lahars can threaten communities along the middle and lower slopes and downstream of (river) channels with inundation, burial, and wash away," the institute said, while urging the provincial authorities "to move residents to high grounds should heavy rains occur."
According to official data, the ongoing eruption displaced thousands of villagers. The evacuees are now housed in government-run temporary shelters around the province.
