|BULUSAN VOLCANO ADVISORY 13 July 2014 10 A.M.|
This is a notice of increasing activity of Bulusan Volcano (12.7667°N, 124.0500°E). For the past few days, above background level of seismic activity was recorded by the Bulusan Seismic network. During the 24-hour observation period, the seismic network detected thirteen (13) volcanic earthquakes. Ground deformation data from continuous GPS and precise leveling survey also indicate that the volcano is slightly inflated.
Although Alert Level 0 status currently prevails 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 and hazardous steam-driven or phreatic eruptions. Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as ejecta from any sudden eruption can 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.
