Taal is showing more signs of unrest with the monitoring network on the volcano recording over 51 volcanic earthquakes over a 24-hour period on Wednesday.

“In the past 24-hour period, the Taal Volcano Network recorded 51 volcanic earthquakes, including 41 episodes of volcanic tremor having durations of one to four  minutes,” Philippine Institute of Volcanology and Seismology (Phivolcs) said in its latest bulletin on Taal Volcano.

The agency said volcanic earthquakes have increased over the past three days, and has maintained Alert Level 2 over Taal, indicating “increased unrest.”

”DOST (Department of Science and Technology)-Phivolcs has raised the level to Alert Level 2. However, despite these activities, evacuation is still not recommended and the public is advised not to go to the Volcano island which is classified as a permanent danger zone,” Phivolcs said.

”Local governments are still advised to prepare for any possible minor ashfalls, earthquakes, and phreatic explosions. This also includes continuous assessment and strengthening of preparedness. Civil Aviation authorities are to advise and maintain pilots for getting close to the volcanic island to prevent and possible ash and ballistic fragments that can cause hazards to their aircraft,” it added.

Phivolcs said it will continue to closely monitor Taal Volcano activities including any new possible changes on its crater.
