Mayon volcano (Luzon Island, Philippines) activity update: inflation continues
Tue, 18 Feb 2020, 11:1011:10 AM | BY: MARTIN
PHIVOLCS reported that the seismic station records 3 volcano-tectonic earthquakes during the last 24 hours.

Additionally recorded emissions of gas and steam plumes. The plumes were dispersed towards the west and southwest direction.
Sulfur dioxide (SO2) emissions reached to a 288 tonnes/day on 17 February.
Recent electronic tilt data showed inflation of the middle to upper portions of the volcanic edifice that began in the last quarter of 2019.
The warning bulletin states that ballistic impacts of volcanic bombs, pyroclastic and lava flows could affect an area of about 6 km distance from the crater.

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
