  • MAYON VOLCANO BULLETIN 11 December 2011 8:00 A.M.

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

      Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network detected one (1) volcanic earthquake during the past 24 hours. Moderate emission of white steam clouds could be observed drifting west-southwest, but crater glow could not be observed due t...
  • TAAL VOLCANO BULLETIN 09 December 2011 8:00 A.M.

      Taal Volcano’s (14.0000°N, 120.9833°E) seismic network detected one (1) volcanic earthquake during the past 24 hours. Field measurements on 06 December 2011 at the western sector of the Main Crater Lake yielded very slightly increased water temp...
  • BULUSAN VOLCANO BULLETIN 09 December 2011 8:00 A.M.

      Bulusan Volcano’s (12.7667°N, 124.0500°E) seismic network detected four (4) volcanic earthquakes during the past 24 hours. During cloud breaks, steaming activity at the known active vents was observed to vary from no steaming to weak and driftin...

    Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network detected one (1) volcanic earthquake and four (4) rockfall-related events during the past 24 hours. Steaming activity and crater glow could not be observed due to thick clouds covering the summit...
  • BULUSAN VOLCANO BULLETIN, 08 December 2011 8:00 A.M.

    Bulusan Volcano’s (12.7667°N, 124.0500°E) seismic network detected one (1) volcanic earthquake during the past 24 hours. Steaming activity could not be observed due to thick clouds covering the summit. Ground deformation survey (precise leveling) last...

    Taal Volcano’s (14.0000°N, 120.9833°E) seismic network detected two (2) volcanic earthquakes during the past 24 hours. Field measurements on 06 December 2011 at the western sector of the Main Crater Lake yielded slight increased water temperature of 3...
  • BULUSAN VOLCANO BULLETIN, 07 December 2011 8:00 A.M.

    Bulusan Volcano’s status remains at Alert Level 1. Entry into the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited due to sudden steam and ash eruptions.  Due to the prevailing wind direction, residents in the northwest and southwe...
