BULUSAN VOLCANO BULLETIN
Bulusan Volcano’s (12°46.2’N, 124°03’E) seismic monitoring network recorded two (2) rockfall events during the past 24 hours. Moderate emmissions of white steam plumes, 100 meters high, that drifted towards the southeast were observed coming from the west-northwest and southwest vents. Precise leveling surveys on May 5-14, 2015 indicate very slight inflation of the volcano’s edifice relative to March 2015.
A steam-generated explosion at the central Philippines’ Bulusan volcano caused ash to rain down on several communities. The blast was caused by rainwater seeping into superheated areas within the volcano. The resulting steam built up pressure, eventually breaking through the lava dome and shooting a plume of ash from previous eruptions high above the summit.
A similar blast in 2011 sent several people to hospitals, suffering from respiratory distress after inhaling ash. But residents this time were urged to wear face masks as a precaution.
Alert Level 1 (abnormal) remains in effect over Bulusan Volcano.
