  • BULUSAN VOLCANO BULLETIN 01 October 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...
  • KANLAON VOLCANO BULLETIN 01 October 2017 08:00 A.M.

    Kanlaon Volcano’s seismic monitoring network recorded fourteen (14) 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 measuremen...
  • MAYON VOLCANO BULLETIN 01 October 2017 8:00 A.M.
