BULUSAN VOLCANO BULLETIN 09 November 2015 8:00 A.M.
Bulusan Volcano’s seismic monitoring network recorded thirteen (13) volcanic earthquakes during the past 24 hours. Steaming activity could not be observed due to thick rain clouds covering the summit. Precise leveling survey results from September 1-6, 2015 indicated slight inflationary changes of the volcano’s edifice relative to July 2015, although ground deformation measurements from GPS data indicated a slight deflationary trend since August 2015.
Alert Level 1 (abnormal) remains in effect over Bulusan Volcano. This indicates that hydrothermal processes are underway beneath the volcano that may lead to steam-driven eruptions. The local government units and the public are reminded that entry to the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited due to the possibility of sudden and hazardous steam-driven or phreatic eruptions. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as ash from any sudden phreatic eruption can be hazardous to aircraft.
