At least 29 small phreatomagmatic bursts were recorded from Taal Volcano's Main Crater lake, the Philippine Institute of Volcanology and Seismology (Phivolcs) reported on Saturday, Oct. 22.

In its 5 am advisory, Phivolcs said the bursts were observed since 5 am on Friday, producing steam-rich plumes that reach 3,000 meters tall and drifting west-northwest.

Two volcanic earthquakes were recorded.

Philvocs also observed light inflation of TVI and Western Taal Caldera, while deflation of Eastern Taal Caldera.

It strictly prohibits individuals from entry into the Permanent Danger Zone or PDZ, particularly the vicinities of the main crater and the Daang Kastila fissure, and occupancy and boating on Taal Lake.

Civil aviation authorities are directed to advise pilots to avoid flying close to the volcano as the airborne ash and ballistic fragments from any sudden eruption could be hazardous to aircraft.

In its 2 pm bulletin on Friday, Phivolcs said Alert level one prevails over Taal Volcano as it is still in abnormal condition and it has yet to cease from unrest nor threat of eruption.

“Should current phreatomagmatic activity worsen or pronounced changes in monitored parameters forewarn of increasing unrest, the Alert Level may be raised to Alert Level 2,“ it added.

Local government units are advised to “continuously assess previously evacuated barangays around Taal Lake for damages and road accessibilities and to strengthen preparedness, contingency and communication measures in case of renewed unrest.“
