  • TAAL VOLCANO BULLETIN 14 September 2011 8:00 A.M.

    Taal Volcano’s (14.0000°N, 120.9833°E) seismic network detected two (2) volcanic earthquakes during the past 24 hours.  Field measurements on 13 September 2011 at the western sector of the Main Crater Lake yielded increased water temperature of 33.6...
  • MAYON VOLCANO BULLETIN 14 September 2011 8:00 A.M.

    Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network detected eight (8) volcanic earthquakes during the past 24 hours.  Weak to moderate emissions of white steam that crept downslope to the northeast could be observed from the summit crater yester...
  • BULUSAN VOLCANO BULLETIN 14 September 2011 8:00 A.M.

    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 d...

    Taal Volcano’s (14.0000°N, 120.9833°E) seismic network did not detect any volcanic earthquake during the past 24 hours.  Field measurements on 06 September 2011 at the eastern sector of the Main Crater Lake yielded slightly increased water temperatur...
  • BULUSAN VOLCANO ADVISORY 12 September 2011 8:00 A.M.

    A marked increase in seismicity of Bulusan Volcano (12.7667°N, 124.0500°E) has been indicated by eleven (11) ) volcanic earthquakes recorded by the seismic network during the past 24 hours. During cloud breaks, weak to moderate emission of white steam w...

    Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network detected two (2) volcanic earthquakes and two (2) rockfall-related events during the past 24 hours.  During cloud breaks, weak emission of white steam that drifted to the east-northeast was obse...
  • MAYON VOLCANO BULLETIN 11 September 2011 8:00 A.M.

    Mayon Volcano's (13.2500°N, 123.6833°E) seismic network detected three (3) volcanic earthquakes and four (4) rockfall-related events during the past 24 hours.  Moderate emission of white steam drifting to the north-northwest could be observed from the ...
