MANILA — The Philippine Institute of Volcanology and Seismology reported Saturday (11 April 2020) 13 volcanic earthquakes during a 24-hour observation period at Taal volcano causing it to raise Alert Level 1.

The Phivolcs said weak steams were observed coming off from fissure vents along the Daang Kastila trail rising 20 meters high before drifting southwest.

Per Philvolcs, an Alert Level 1 condition is considered as “Abnormal.”

Alert Level 1 may cause “sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within the Taal Volcano Island (TVI) the Philvolcs said.

Entry into TVI, Taal’s Permanent Danger Zone or PDZ, especially the vicinities of the Main Crater and the Daang Kastila fissure were also strongly prohibited.

Local government units were also directed by Phivolcs 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.

Ground displacement across fissures, possible ashfall, and minor earthquakes may also occur under Alert Level 1 it said.

The Phivolcs also informed civil aviation authorities to advise pilots to avoid flying close to the volcano as airborne ash and ballistic fragments from sudden explosions and wind-remobilized ash may pose hazards to aircrafts. (ia)
