Mayon volcano (Luzon, Philippines) activity update: faint crater glow, continuous ground deformation

Пт, 7 мая 2021, 09:30
The volcano remains at light volcanic unrest, with faint glow from the crater visible at night and continuing ground deformation detected by instruments of the Philippine Institute of Volcanology and Seismology (PHIVOLCS).
According to the latest bulletin released by PHIVOLCS on 7 May 2021 at 8:00 am, the Mayon Volcano Monitoring Network has not detected volcanic earthquakes during the last 24 hours. The latest measurement of sulfur dioxide emissions last 8 March 2021 was at an average of 80 tonnes/day.
Precise Leveling surveys on 4-11 March 2021 showed slight inflation of the edifice as compared to the December 2020 survey. Continuous GPS monitoring showed that the edifice is still inflated as compared to July 2019 despite a period of deflation since July-August 2020. Short-term inflation has been ongoing since November 2020. Electronic tilt monitoring showed deflation of the edifice with short-term inflation of the northwestern slopes since December 2020.
PHIVOLCS maintains the Alert Level 1 at Mayon volcano. This means that it is at at unrest, but no eruption is expected in the near future.
