  • MAYON VOLCANO BULLETIN 30 April 2017 8:00 A.M.

    Mayon Volcano’s seismic monitoring network did not detect any volcanic earthquake during the past 24 hours. Weak emission of white steam plumes that drifted southwest and south-southwest was observed. Precise leveling data obtained on February 5-10, 201...
  • KANLAON VOLCANO BULLETIN 30 April 2017 08:00 A.M.

    Kanlaon Volcano’s seismic monitoring network did not detect any volcanic earthquake during the past 24 hours. No steaming was observed during times when the summit crater was visible. Sulfur dioxide (SO2) emission was measured at an average of 1 tonne p...
  • BULUSAN VOLCANO BULLETIN 30 April 2017 8:00 A.M.

    Bulusan Volcano’s seismic monitoring network did not detect any volcanic earthquake during the past 24 hours.  Weak emission of white steam plumes that rose up to 50 meters and drifted west-southwest was observed coming from the active vents. Sulfur di...
