Kanlaon volcano (Philippines) - Smithsonian / USGS Weekly Volcanic Activity Report for 10 February-16 February 2021 (Continuing Activity)
Wed, 10 Feb 2021, 06:00
06:00 AM | BY: VNThe sulfur dioxide emission rate on 13 February was 1,130 tonnes per day, the highest value recorded this year; sulfur dioxide emissions had been higher than background levels of 300 tonnes/day since June 2020. Ground deformation data from continuous GPS and tilt measurements indicated slight inflation of the lower and middle flanks since June 2020. Increased seismic activity continued through 16 February; from 0800 on 14 February to 0800 on 16 February there were a total of 59 earthquakes.
The Alert Level remained at 1 (on a scale of 0-5) and PHIVOLCS reminded the public to remain outside of the 4-km-radius Permanent Danger Zone.

PHIVOLCS recorded 4 volcanic earthquakes beneath Canlaon volcano over the past 24 hours. Moderate emission of white steam-laden plumes that rose 500 meters before drifting northwest and northeast was observed. Sulfur dioxide (SO2) emission was measured at an average of 1012 tonnes/day on 02 August 2020. GPS measurements indicate slight inflation of the lower and mid slopes since May 2020, while the southeastern flanks recorded inflation on the lower to mid slopes that began on June 21, 2020. PHIVOLCS state that these parameters may indicate hydrothermal or magmatic processes occurring beneath the edifice. ... Read all
