Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network did not detect any volcanic earthquake during the past 24-hour observation period. Moderate emission of white steam plumes drifting west-northwest, north-northwest and east-northeast was observed. The crater was visible last night but no glow could be observed. Sulfur dioxide (SO2) emission rate on 11 May 2012 was measured at an average of 126 tonnes per day. Ground deformation survey (precise levelling) last 01-04 May 2012 showed no significant change compared to February 2012.
