Alert Level 2 raised over Taal Volcano amid ‘increasing unrest’
MANILA, Philippines – Alert Level 2 has been raised over Taal Volcano on Tuesday (March 9) amid “increasing unrest.”
In its latest bulletin, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said that a total of 28 volcanic tremor episodes, four low-frequency volcanic earthquakes, and one hybrid earthquake at shallow depths of less than 1.5 kilometers beneath Taal Volcano Island were recorded in the past 24 hours.
Also, volcanic tremors have increased seismic energy compared to previously recorded episodes and ranged between three to 17 minutes in duration.
“The total number of volcanic tremor events has risen to 866 since the onset of increased activity on February 13,” PHIVOLCS said.
“In addition to these, a total of 141 low-frequency volcanic earthquakes have occurred within one kilometer depths beneath the volcano island and immediate vicinity,” it added.
The agency said seismic activity in the past month indicates increased magmatic and hydrothermal activity at shallow depths beneath the volcano island.
This means there is probable magmatic activity that may or may not lead to an eruption, the agency noted.
With this development, the PHIVOLCS stressed that entry into Taal Volcano Island remains strictly prohibited as it is considered a permanent danger zone.
Evacuation, however, is not yet recommended, the agency said,
