Updates on volcanic activity (Smithsonian)

The Smithsonian/USGS Weekly Volcanic Activity Report provides information about global volcanism on a weekly basis. Latest Taal report has been published on 17 Feb 2021 08:52.
PHIVOLCS reported that geochemical data collected from Taal?s Main Crater lake indicated a continuous acidification of the water from pH 2.79 to 1.59 between January 2020 and February 2021. A maximum temperature of 77.1 degrees Celsius was unseasonably high, and carbon dioxide/hydrogen sulfide gas flux ratios were consistent with shallow magma degassing. Tilt data indicated minor deflation around Main Crater, though minor inflation was consistently recorded across the Taal region as indicated by analysis of GPS data, InSAR, and microgravity changes. A total of 68 relatively weak tremor signals were detected during 13-15 February; 50 of those were recorded during 0500-1500 on 15 February. The events on 15 February ranged in duration from two to five minutes and occurred at depths less than 1 km. The depth and location of the earthquakes suggested increased hydrothermal activity beneath Taal Volcano Island. Increased seismic activity continued through 16 February; from 0800 on 15 February to 0800 on 16 February there were a total of 98 earthquakes. The Alert Level remained at 1 (on a scale of 0-5) and PHIVOLCS strongly recommended no entry onto the island, and the Main Crater and the Daang Kastila fissure (along the walking trail) was strictly prohibited.
