  • MAYON VOLCANO BULLETIN, 08 September 2011, 8:00 A.M.

    Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network detected one (1) rockfall event and one (1) volcanic earthquake during the past 24 hours.  Moderate emission of white steam that crept downslope to the northeast could be observed. Fair crater g...

    Bulusan Volcano’s (12.7667°N, 124.0500°E) seismic network did not detect any volcanic earthquake during the past 24 hours. Steaming activity could not be observed due to thick clouds that covered the summit crater and known thermal vents.  Ground def...
  • TAAL VOLCANO BULLETIN, 07 September 2011, 8:00 A.M.

    Taal Volcano’s (14.0000°N, 120.9833°E) seismic network detected two volcanic earthquakes during the past 24 hours.  Field measurements on 30 August 2011 at the western sector of the Main Crater Lake yielded slightly decreased water temperature of 32....
