The latest Mayon bulletin, no. 9, reports little change in the volcano’s behaviour over the previous 24 hours:
Seismic activity remained elevated in number and size as the seismic network detected a total of 1,266 volcanic earthquakes. Many of these volcanic earthquakes were recorded at maximum deflection and have continuously occurred since 12:21 PM, 20 December 2009. Harmonic tremors were still continuously being recorded.
Sulphur dioxide emission remained high at 6,529 tonnes/day. An intensified crater glow was observed during a break in the cloud cover, and booming and rumbling noises continued to be audible. Lava continued to flow downslope to a distance of about 5 km from the crater.
The Manila Bulletin is reporting that an increase in alert level at Mayon from 4 to 5 is ‘imminent’. Level 5, the highest level, indicates that a hazardous eruption is ongoing, and presently, for all the disruption, that is not the case. There would have to be a marked upswing in activity from Mayon before level 5 would be justified – which is precisely what the Phivolcs official quoted in the story says. Meanwhile, Phivolcs has warned people to the south of the volcano to stay clear of potential lahar channels.
Fears of infectious disease among the c. 47,000 evacuees crowded into shelters have led to the deployment of extra medical teams by the Philippines Department of Health. The psychological health of the thousands of people now facing a Christmas away from their homes and in the shelters is also being considered: soldiers in Santa hats have been distributing presents to children, and an appeal has gone out for ‘clowns and actors’ to provide entertainment and lift the evacuees’ spirits. Those who have ignored the evacuation order receive no such consideration: the authorities are considering making anyone who insists on staying within the danger zone sign a waiver to the effect that anything that happens to them when the volcano erupts is their own responsibility.
