  • MAYON VOLCANO BULLETIN 23 September 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.  Weak emission of white steam that drifted north-northwest and north-northeast could be observed from the crater during cloud bre...
  • BULUSAN VOLCANO BULLETIN 23 September 2011 8:00 A.M.

    Bulusan Volcano’s (12.7667°N, 124.0500°E) seismic network detected three (3) volcanic earthquakes during the past 24 hours. Wispy to weak steaming could be observed on the summit crater and known thermal vents.  Ground deformation survey (precise l...
