  • MAYON VOLCANO BULLETIN 1 February 2012 8:00 A.M.

      Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network did not detect any volcanic earthquake during the past 24 hours. Steaming activity and crater glow could not be observed due to thick clouds covering the summit area. Measurement of sulfur di...
