DOST-PHIVOLCS MAYON VOLCANO BULLETIN 01 October 2014 8:00 A.M. Mayon Volcano’s (13.2500°N, 123.6833°E) seismic network recorded two (2) volcanic earthquakes and two (2) rockfall events during the past 24-hour observation period. During good visibility moderate emission of white steam plumes drifting towards southeast and southwest was observed. Rain clouds covered the summit preventing visual observation. Sulfur dioxide (SO2) flux was measured at an average of 1421 tonnes/day on 29 September 2014. Ground deformation data showed no significant change from August 2014 based on September 2014 precise leveling survey although the edifice remains inflated compared to baseline measurements. Tilt data also indicate continuous inflation at the base of the edifice since August 2014. All the above data indicate that the volcano is still in a state of unrest due to the movement of potentially eruptible magma.
