TALISAY, BATANGAS — Local authorities here are cautioning residents to be prepared following a warning from the Philippine Institute of Volcanology and Seismology (Phivolcs) that those residing near Taal volcano must observe precautions due to ground displacement across fissures, possible ash fall and minor earthquakes from the volcano.
Phivolcs had earlier revealed that an increase of up to 17,141 tons of volcanic sulfur dioxide (SO2) gas emission daily has been recorded in the volcano and airborne volcanic gas is expected to be drifted to the general east to west of Taal Volcano Island based on air parcel trajectory data.
The institute’s seismology bureau disclosed that an average of 6,041 SO2 flux ton/day has been recorded since July—an increase from the average of 1,289 tons/day between May and mid-July.
It added that there is also a visible increase of degassing in the form of upwelling in the volcano’s main crater lake and voluminous steam-rich plume activity, with a total of three volcanic tremors that lasted nine minutes, in the previous 24-hour observation period.
Once again, Phivolcs reminded the public that Taal Volcano is still under Alert Level 1, which means it is still in its unrest conditions.
“Should an uptrend or pronounced change in monitored parameters forewarn of renewed unrest, the Alert Level may be raised back to Alert Level 2,” it noted.
Local government units have been advised to continuously assess previously evacuated barangays around Taal Lake for damage and road accessibilities and to strengthen preparedness, contingency and communication measures in case of renewed unrest. (ai/mtvn)
