Philippines’ Taal Volcano erupts twice in four days, alert level may be raised

On October 5th, we received news from the Philippine Institute of Volcanology and Seismology (PHIVOLCS) regarding the latest activity of Taal Volcano. Can you tell us about the recent eruption?

Absolutely. PHIVOLCS reported that Taal Volcano erupted once again, producing a plume that soared up to 2,000 meters high and lasted for about four minutes. This eruption marks the second time in just four days that the volcano has shown signs of activity.

What caused this latest eruption?

According to PHIVOLCS, the eruption may have been triggered by an unexpected interaction between water and shallow magma located beneath the main crater of Taal. Interestingly, this shallow magma has been continuously emitting sulfur dioxide for the past three years. Since January, the data indicates that Taal Volcano has averaged sulfur dioxide emissions of around 6,673 tons per day.

What is the current alert level for Taal Volcano?

Currently, Taal Volcano is at Level 1, which is considered a “low-level unrest.” However, PHIVOLCS has cautioned that if the magmatic activity continues or intensifies, there’s a possibility that the alert level could elevate to Level 2. For context, their alert system ranges from Level 0, meaning “no alert,” to Level 5, which indicates “the volcano is erupting.”

Could you give us a brief overview of previous eruptions leading up to this one?

Yes, prior to this recent activity, Taal Volcano experienced an 11-minute eruption on October 2nd. Following that event, President Marcos addressed the media and reassured the public that the volcanic unrest remains “within manageable limits.”

Have there been any reports of casualties or evacuation orders issued?

At this point in time, local authorities have not reported any casualties nor have they issued any evacuation orders. However, PHIVOLCS has advised nearby communities to stay alert and be mindful of the potential health risks due to elevated sulfur dioxide emissions.

Finally, could you give us some perspective on Taal Volcano’s activity in the region?

Certainly! Taal Volcano is situated about 60 kilometers south of Manila and is recognized as one of the most active volcanoes among the more than 20 known active volcanoes in the Philippines. Its activity continues to be closely monitored by both PHIVOLCS and local authorities.
