  • BULUSAN VOLCANO BULLETIN 27 May 2017 8:00 A.M.

    Bulusan Volcano’s seismic monitoring network recorded one (1) 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...
