Philippine Institute of Volcanology and Seismology (Phivolcs) recorded up to 240 earthquakes around Taal Volcano and nearby areas, Tuesday.
According to Phivolcs Director Renato Solidum, 140 of these were felt.
Phivolcs recorded 4.1 as the strongest, while intensities range from Intensity 1 to 5.
Earthquakes are still expected due to the Taal Volcano’s eruption, which is already at Alert Level 4.
Earlier, Solidum said he had not seen any decline in Taal’s volcanic activity.
Authorities advised those who are in the danger zones and nearby areas to evacuate and not to return to their homes yet.
75 volcanic earthquakes recorded in Taal Volcano on Monday
According to the 8 AM Taal Volcano Bulletin of the Phivolcs yesterday, of the 75 quakes, 32 recorded intensities.
Intensity 2 to 5 was recorded in Tagaytay City, Cabuyao, Laguna, Talisay, Alitagagag, Lemery, and Bauan in Batangas.
Magma volcanic eruption was recorded at 2:49 am, and 4:28 am.
The alert level 4 remains in Taal, and according to the Phivolcs, it is still possible to erupt in the next few hours or days.
A volcano-tectonic shock is an earthquake caused by the movement of magma beneath the surface of the Earth. The movement results in pressure changes where the rock around the magma has experienced stress.
At some point, this stress can cause the rock to break or move. This seismic activity is used by scientists to monitor volcanoes. The earthquakes may also be related to dike intrusion or occur as earthquake swarms.
Volcano tectonic seismicity is a vital tool in being able to predict the eruptions of volcanoes. Seismic activity occurs as a precursor to most large eruptions.
