The Philippine Institute of Volcanology and Seismology (PHIVOLCS) observatory recorded five mild phreatic bursts from the Main Crater Lake within the Taal caldera between 01:10 AM and 04:37 PM yesterday.
The explosive activity was accompanied by emissions of steam-laden plumes, generating column height between 300 and 2,100 meters above the fumarolic vents drifting east-northeast. Events were steam-driven only, caused by overheated water flashing to steam.
Sulfur dioxide (SO2) emissions reached to a 1354 tonnes/day on 30 September.
The seismic station registered 6 two-to-ten-minute-long volcanic tremor events over the past 24 hours.
The latest maximum Main Crater Lake temperature reached to a 72.7 °C on 20 February.
The short-term electronic tiltmeter and GPS measurements found the northern and southeastern edifice area deflated. However, from a long-term point of view, instruments continue to register the ongoing uplift of the Taal caldera.
The alert level for the volcano remains at Level 1.
