This is a notice of increasing activity of Bulusan Volcano (12.7667°N, 124.0500°E).  For the past two weeks, above background level of seismic activity was noted. During the 24-hour observation period, the seismic network detected ten (10) volcanic earthquakes. Ground deformation survey (precise leveling) conducted last 14-18 November 2011 indicated that the volcano is slightly inflated.

Alert Level 1 status is strongly reiterated over Bulusan Volcano. 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 steam and ash eruptions. Civil aviation authorities must also warn pilots to avoid flying close to the volcano’s summit as ejecta from sudden eruptions may be hazardous to aircraft. Furthermore, people living within valleys and along river/stream channels 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 activity and any new development will be relayed to all concerned.
