Mayon volcano on the island of Luzon in the Philippines has been showing signs of abnormal activity, according to reports from Phivolcs (the Philippine Institute of Volcanology and Seismology – their unreliable website is here). A ‘rise in volcanic quakes’ has been recorded according to Phivolcs sources quoted in the local press, with 13 earthquakes over the last 24 hours, moderate steaming, and a glow in the crater being observed. Phivolcs is carrying out further surveys, including an overflight, and is monitoring the volcano 24 hours a day.
As yet the alert level for Mayon remains at level 1. A six-kilometre ‘permanent danger zone’ and a seven-kilometre ‘extended danger zone’ are in force around the volcano, and tourists and residents are being advised to keep their distance and respect these exclusion zones.
