Bulusan Volcano’s seismic monitoring network recorded four (4) volcanic earthquakes during the past 24 hours. Steaming activity could not be observed due to thick clouds covering the summit. Precise leveling data obtained on 27 April to 5 May 2016 indicated slight deflationary changes of the edifice relative to February 2016. This is consistent with ground deformation data from continuous GPS measurements as of 01 August 2016 that showed deflationary trends since May 2016.

Alert Level 1 (abnormal) remains in effect over Bulusan Volcano. This indicates that hydrothermal processes are ongoing beneath the volcano that may lead to more 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. 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.
