MANILA, Philippines — Existing fissures in areas near Taal Volcano widened by a few centimeters, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Friday.

In its 8 a.m. update, the state seismic network said existing cracks in barangays of Lemery, Agoncillo, Talisay and San Nicolas in Batangas province have been observed to widen.

Alert level 4 is still raised over the volcano, which means that hazardous explosive eruption is possible within hours to days.

The volcano's main crater continued to emit steady steam and infrequent weak explosions in the past explosions.

The latest emissions generated dark gray ash plumes 100 to 800 meters high and dispersed ash southwest to west of the main crater, Phivolcs said.

Phivolcs also observed that the shoreline around the whole of Taal Lake has been receding.

From 5 a.m. on Thursday until 5 a.m. Friday, Phivolcs recorded 65 volcanic earthquakes, two of which with magnitudes 1.3 to 3.1 and were both felt at Intensity I.

It also noted that the Taal Volcano network recorded 944 volcanic earthquakes with 29 low-frequency earthquakes.

"Such intense seismic activity likely signifies continuous magmatic intrusion beneath the Taal edifice, which may lead to further eruptive activity," Phivolcs said.

The towns of Laurel, Taal, Agoncillo and Talisay have been on lockdown to prevent people from entering the "off limits zone."

The four towns are within the 14-kilometer danger zone, which is susceptible to ballistic projectiles, base surges and volcanic tsunami.

The Philippine Institute of Volcanology and Seismology reports that Taal Volcano's daily sulfur dioxide emissions (SO2) reached 2887 tonnes.

It observes upwelling of hot volcanic fluids in the Main Crater Lake as well as volcanic smog or vog.

The volcano's emissions are also 2400 meters tall. — Rosette Adel

The Philippine Institute of Volcanology and Seismology releases time-lapse snapshots of degassing activity from the Taal Main Crater and volcanic smog or vog formation on Sunday.

These were taken from 5:45 a.m. to 11:42 a.m. by the Mt. Macolot, Cuenca, Batangas station (VTCU) IP Camera.

The Philippine Institute of Volcanology and Seismology records daily sulfur dioxide emissions that reached 2730 tonnes / day (22 September 2023).

It also observes upwelling of hot volcanic fluids in the Main Crater Lake and observed VOG.

Phivolcs adds that there is a ong-term deflation of the Taal Caldera; short-term inflation of the northern flanks of the Taal Volcano Island.
