  • KANLAON VOLCANO BULLETIN 05 September 2017 08:00 A.M.

    Kanlaon Volcano’s seismic monitoring network recorded eleven (11) volcanic earthquakes during the past 24 hours. No degassing activity was observed during times when the summit crater was visible. Ground deformation data from continuous GPS measurements...
  • MAYON VOLCANO BULLETIN 04 September 2017 8:00 A.M.

    Mayon Volcano’s seismic monitoring network recorded one (1) volcanic earthquake during the past 24 hours. Moderate emission of white steam plumes that drifted northeast and southwest was observed.. Precise leveling data obtained on May 11-18, 2017 indic...

    Kanlaon Volcano’s seismic monitoring network recorded twelve (12) volcanic earthquakes during the past 24 hours. No degassing activity was observed during times when the summit crater was visible. Ground deformation data from continuous GPS measurements...
  • BULUSAN VOLCANO BULLETIN 04 September 2017 8:00 A.M.

    Bulusan Volcano’s seismic monitoring network did not detect any volcanic earthquake during the past 24 hours. Degassing at the active vents could not be observed due to thick clouds covering the summit. Sulfur dioxide (SO2) emission was measured at an a...
