Bulusan Volcano’s seismic monitoring network recorded fifteen (15) volcanic earthquakes during the past 24 hours. Wispy to weak emission of white steam plumes that drifted toward southwest was observed. Precise leveling survey results from February 23-28, 2016 indicated slight deflationary changes of the volcano’s edifice relative to December 2015, consistent with ground deformation measurements from continuous GPS data since February 2016.

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 into 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. Furthermore, people living within valleys and along river/stream channels especially on the southwest and northwest sector of the edifice should be vigilant against sediment-laden stream flows and lahars in the event of heavy and prolonged rainfall. DOST-PHIVOLCS is closely monitoring Bulusan Volcano’s condition and any new development will be relayed to all concerned.
