Mayon volcano (Luzon, Philippines) activity update: situation unchanged

The volcano’s activity remains stable, but above background levels. No quakes were detected during the past 24-hour observation period. PHIVOLCS reported „Moderate emission of white steam-laden plumes that crept downslope before drifting to the general northwest was observed. Faint crater glow from the summit could be observed at night.“
„Continuous GPS monitoring indicate that the edifice is still inflated relative to July 2019 despite a period of general deflation since July-August 2020 and has been undergoing short-term inflation since November 2020. Deflation of the edifice with short-term inflation of the northwestern slopes since December 2020 has also been recorded by electronic tilt monitoring.“
