The latest 8 AM bulletin from the institute states that for the past 24 hours, the Main Crater has been described by weak to moderate emission of white steam-laden plumes 50 to 500 meters high that drifted southwest.

The average for the emission of sulfur dioxide slightly dropped to 141 tonnes per day compared to 153 tonnes per day from yesterday’s 8 AM bulletin.

The Philippine Seismic Network (PSN) recorded six volcanic earthquakes as of 5 AM January 22 to 5 AM January 23. These were registered at magnitudes 1.5 to 3.4.

This adds up to a total of 731 volcanic earthquakes overall, where 176 of them registered at magnitudes 1.2 – 4.1 felt at Intensities I – V.

The Taal Volcano Network, which can small earthquakes undetectable by the PSN, plotted at abot 467 earthquakes, which includes 8 low-frequency tremors.

This intense activity will likely signify continuous magmatic intrusion beneath the Taal edifice, which may lead to further eruptive activity.

As per the bulletin, Taal Volcano is still under Alert Level 4. This means that we could expect a hazardous explosive eruption within hours to days.

The institute strongly reiterate the total evacuation of Taal Volcano Island and high-risk areas as identified in the hazard maps within the 14-km radius from Taal Main Crater and along the Pansipit River Valley.

Citing PAGASA’s wind forecast, should the eruption plume remains below five kilometers, the ash will be drifted to the municipalities west and northwest of the Main Crater.

Should a major eruption occur, however, and the eruption plume exceeds 7 kilometers. ash will also be drifted over parts of Laguna and Quezon provinces.

What do you think? How will you react to this? Let us know more about it.
