  • MAYON VOLCANO BULLETIN 29 October 2011 8:00 A.M.

    Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network detected one (1) rock fall related event during the past 24 hours. Steaming activity and crater glow could not be observed due to thick clouds that covered the summit area. Measurement of sulfu...
