PHIVOLCS issues lahar advisory near Mayon Volcano due to Tropical Storm Kristine

Residents near Mayon Volcano in Albay province have been advised to remain vigilant due to lahar advisories issued by PHIVOLCS amid the approach of Tropical Storm Kristine.

Over the past two days, a total of 36 rockfall events occurred at Mayon Volcano before Severe Tropical Storm Kristine made landfall, with eight recorded on Wednesday and 28 on Tuesday.

Tropical Storm Kristine caused widespread flooding across the Bicol Region, resulting in non-eruption lahars up to one meter high engulfing vehicles in Barangay Masarawag, Guinobatan, and PHIVOLCS issued an advisory warning of potential sediment-laden streamflows.

Local government units have been instructed to prepare schools for use as temporary shelters, while the Philippine Red Cross deployed 143 volunteers from its Albay Chapter to assist with clearing operations in affected areas.

Mayon Volcano remains at Alert Level 1 with a sulfur dioxide flux release of 1,064 tonnes on Monday, October 21, and entry into the six-kilometer radius permanent danger zone is prohibited.
