MANILA, Philippines – The Philippine Institute of Volcanology and Seismology (PHILVOLCS)’s latest earthquake information recorded multiple seismic events in Batangas, which is near the Taal Volcano, on April 22.
In the photo below, there have been already 14 earthquake occurrences as of 12:41 PM.
The Taal Volcano Bulletin released at 8am of April 22 by PHILVOLCS indicated:
In the past 24-hour period, the Taal Volcano Network recorded eight (8) volcanic earthquakes that are mainly associated with rock-fracturing processes beneath and around the edifice. Weak steaming or fumarolic activity was observed from vents on the Main Crater and from fissure vents along the Daang Kastila trail.
According to Michigan Tech University’s Geological and Mining Engineering and Sciences Department, volcanic earthquakes can “cause land to subside and can produce large ground cracks.” There are types, however, that “don’t indicate that the volcano will be erupting but can occur at anytime.”
Furthermore, a series of earthquake can indicate that a volcano is likely about to erupt. These happen when there is an unsteady transport of magma inside a volcano.
PHILVOLCS already raised Alert Level 1 (Abnormal) over Taal Volcano. The public are to expect “sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall and lethal accumulations or expulsions of volcanic gas” to arise within the Taal Volcano Island (TVI).
Authorities strictly prohibit entry into TVI and its Permanent Danger Zone.
The local government units must also proactively monitor and assess their areas for damages and road accessibility.
LGUs must be prepared for contingency and communication measures as there is a possibility of renewed unrest.
