  • MAYON VOLCANO BULLETIN 31 January 2018 08:00 AM

    At 11:51 AM yesterday, one (1) lava-collapse fed pyroclastic density current or PDC event on Miisi Gully occurred that produced a 1250 meter-high ash cloud that drifted southwest. This was succeeded by two (2) more PDC events on the Basud Gully that laste...
  • KANLAON VOLCANO BULLETIN 31 January 2018 08:00 A.M.

    Kanlaon Volcano's seismic monitoring network recorded one (1) volcanic earthquake during the past 24 hours. Wispy to moderate emission of white steam-laden plumes that rose 300 meters from the summit before drifting southwest was observed during times whe...
  • BULUSAN VOLCANO BULLETIN 31 January 2018 08:00 A.M.

    Bulusan Volcano’s seismic monitoring network recorded three (3) volcanic earthquakes during the past 24 hours. Weak emission of white steam-laden plumes was observed. Precise leveling data obtained on November 20 – 29, 2017 indicated a slight deflatio...
  • MAYON VOLCANO BULLETIN 30 January 2018 08:00 AM

    Beginning 7:50 last night, energetic lava effusion with sporadic lava fountaining events and generation of lava-collapse fed pyroclastic density currents or PDCs or “uson” occurred until 11:06 PM. Although the upper slopes were heavily obscured, the s...
  • KANLAON VOLCANO BULLETIN 30 January 2018 08:00 A.M.
