Mayon volcano (Luzon Island, Philippines): inflation continues; constant glow

DOST-PHIVOLCS recorded two volcanic earthquakes from Mayon Volcano over the past 24 hours. Moderate emissions of steam-laden plumes that crept downslope before drifting to the general west was observed. Inflation of the northern sector of the volcanic edifice that began in the last quarter of 2019 continues. This follows an inflationary trend that began in February 2019. The alert level remains at ALERT LEVEL 2. Read all

Mayon Volcano's seismic monitoring network recorded one volcanic earthquake over the last 24 hours. DOST-PHIVOLCS observed weak steam emissions with plumes drifting east-northeast. Sulfur dioxide (SO2) emissions was measured at 115 tonnes/day on 10 January 2020. Ground deformation data from Precise Levelling surveys obtained on 23 – 30 October 2019 indicate a slight deflation of the edifice relative to 16 – 25 July 2019. However, the volcano generally remains inflated relative to the early 2019 baseline level. This is consistent with recent electronic tilt data. Continuous GPS data also showed inflation of the edifice since February 2019. Read all
