The Philippine Institute of Volcanology and Seismology (Phivolcs) has issued a warning regarding potential lahar and volcanic debris flows from Mount Pinatubo and Taal Volcano. This alert is due to the ongoing heavy rainfall brought by the southwest monsoon, known as "habagat," impacting Luzon. Lahar, a mixture of volcanic ash and water, can create dangerous flows down the volcanoes' slopes, posing risks to surrounding communities. Phivolcs is closely monitoring the situation and advises residents in vulnerable areas to be vigilant. The risk is amplified by the saturation of volcanic deposits from past eruptions. Authorities are prepared to implement evacuation procedures if necessary, prioritizing public safety during the continued heavy rains. Residents near river channels originating from these volcanoes should be particularly cautious.
