  • TAAL VOLCANO BULLETIN, 01 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 29 November 2011 at the eastern sector of the Main Crater Lake yielded a decrease in water temperature from 33....
  • MAYON VOLCANO BULLETIN, 01 DECEMBER 2011, 8:00 A.M.

    Mayon Volcano's (13.2500°N, 123.6833°E) seismic network did not detect any volcanic earthquake during the past 24 hours. Moderate emission of white steam clouds that crept downslope towards west-southwest and west-northwest was observed. Measurement of ...
