48 Volcanic Quakes and 40 Tremor Episodes Recorded at Taal Volcano in 24 Hours

According to the 8:00 AM volcanic bulletin today, March 2, 2021 (Tuesday), of the Philippine Institute of Volcanology and Seismology (PHIVOLCS), forty-eight (48) volcanic earthquakes and forty (40) volcanic tremor episodes that lasted from 1-1.5 minutes were recorded in the past 24 hours.

PHIVOLCS added that activity at the Main Crater consisted of weak emission of steam-laden plumes from fumarolic vents.

Furthermore, as stated in the bulletin, temperature highs of 74.6°C and pH of 1.59 were last measured from the Main Crater Lake respectively on 18 and 12 February 2021.

“Ground deformation parameters from continuous electronic tilt on Volcano Island record a slight deflation around the Main Crater since October 2020 but overall, very slow and steady inflation of the Taal region has been recorded by continuous GPS data after the eruption,” PHIVOlCS added.

Taal at Alert Level 1

Taal Volcano is at Alert Level 1 (Abnormal) and the public is reminded that the following can occur and threaten areas within the Taal Volcano Island (TVI):

• sudden steam-driven or phreatic explosions
• volcanic earthquakes
• minor ashfall
• lethal accumulations or expulsions of volcanic gas

Entry into TVI Prohibited

PHIVOLCS has recommended that entry into TVI, Taal’s Permanent Danger Zone (PDZ), especially the vicinities of the Main Crater and the Daang Kastila fissure, must remain strictly prohibited.

PHIVOLCS Reminders

The following are additional reminders from PHIVOLCS:

• Local government units are advised to continuously assess and strengthen the preparedness of previously evacuated barangays around Taal Lake in case of renewed unrest.
• Civil aviation authorities must 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 aircraft.
