The Philippine Institute of Volcanology and Seismology (Phivolcs) on Thursday, June 8, 2023, warned that a 'hazardous eruption' of Mayon Volcano could be weeks or days away, prompting the local government of Albay to order the mandatory evacuation of residents inside the 6-kilometer radius permanent danger zone. Phivolcs said it observed three fast-moving avalanches of volcanic ash, rock, and gases, known as pyroclastic density currents (PDCs), on Mayon's slopes on Thursday. There are 'increased chances of lava flows and hazardous PDCs … and of potential explosive activity within weeks or even days,' the agency said, raising the alert level from two to three on a scale of zero to five.
