Mayon volcano in the Philippines continues to erupt lava and incandescent rocks onto its slopes and there has been significant ashfall in neighbouring areas, but as yet there has been no large-scale explosive activity. The volcano remains on alert level 3.

Mandatory evacuations of residents from within the Mayon danger zone have been continuing: as of 17:00 local time on 16 December, a total of 30,761 residents had been evacuated according to the Regional Disaster Co-ordinating Council in Bicol. President Arroyo has ordered the military to assist in the evacuation process: ‘The guidance of our president is zero casualty’, says Defence Secretary Norberto Gonzales. A situation report from the Philippines National Disaster Co-ordinating Committee is available at ReliefWeb.

In the daily bulletin from Philippine Institute of Volcanology and Seismology (Phivolcs) issued at 08:00 local time this morning (summarized here), it was reported that 78 high frequency volcanic earthquakes and tremors had been detected over the previous 24 hours, and white steam emissions had reached 200 metres above the summit. Lava flows had reached 700-800 metres downslope from the crater, and detached lava fragments were reported to have generated a secondary pyroclastic surge that caused ashfall in the towns of Camalig and Guinobatan.

The Phivolcs website, by the way, is not working at the moment. [UPDATE 17 December 2009 – it’s working again.]
