Mayon volcano: eruption news and updates
Mayon volcano (Philippines), activity summary 29 Oct - 4 Nov: continuing inflation
Friday Nov 07, 2014 13:14 PM | BY: T
PHIVOLCS reported that during 28 October-4 November white plumes rose from Mayon's crater and drifted SW, WSW, WNW, and NW, sometimes down the flanks. Weak incandescence from the crater was noted at night on 28 October.
A few volcanic earthquakes and rockfall signals were recorded during 29-31 October and 4 November. A 4 November report noted that ground deformation had been detected since the beginning of 2014.
Tilt data from the network on the NW flank indicated continuing inflation since August, subsequent to a period of inflation in June and July. The inflation events were thought to correspond to a magma body, approximately 107 cubic meters, slowly intruding at depth. Precise leveling measurements also indicated sustained inflation. The Alert Level remained at 3 (on a 0-5 scale).
