Two instances of lava flow have been observed at Mayon Volcano today.
The first time was at 9:41 am and the second time was at 10:05 am.
Philippine Institute of Volcanology and Seismology (PHIVOLCS) Director Renato Solidum explains, lava deposits on the crater would sometimes collapse and flow down the slopes.
This activity may go on for a few days.
Alert level 3 is up over Mayon.
This warning means there is increased activity toward a hazardous eruption.
The lava collapse has brought ash falls in the towns of Camalig and Guinobatan in Albay.
Nearly a thousand families have gone to schools that have become evacuation centers.
Classes in these areas were suspended.
The residents who fled were living within the 7-kilometer danger zone of the volcano.
