Philippine scientists warn of another eruption at Taal Volcano

The highest levels of volcanic sulfur dioxide emission recorded at the volcano, which indicates possible eruption, officials said.

Another eruption at the Philippines’ second-most active volcano can occur anytime soon amid “anomalously high” volcanic gas emissions, according to government scientists.

More than 3,000 residents from high-risk villages around Taal Volcano in Batangas province, 66km (41 miles) south of the capital Manila, have fled their homes since Thursday, when the volcano erupted, spewing a dark plume of volcanic gas and steam in the air.

Since then, several bursts of volcanic gas and steam have been generated by Taal.

On Sunday, “the highest levels of volcanic sulfur dioxide gas emission was recorded … at an average of 22,628 tonnes per day, the highest-ever recorded in Taal”, the Philippine Institute of Volcanology and Seismology (Phivolcs) said in a bulletin.

The emissions were accompanied by 26 strong and very shallow low-frequency volcanic earthquakes “associated with magmatic degassing”, it added.

“These observations may indicate that an eruption similar to the July 1, 2021 event may occur anytime soon,” the institute said.

Phivolcs raised the alert at the volcano to level 3, which means that there was “ongoing magmatic extrusion at the main crater that may further drive succeeding explosions”.

Taal last erupted on January 12, 2020, displacing more than 376,000 people from surrounding towns.

At the time, 39 people, in evacuation centres, died due to illness and accidents caused by thick ashfall, according to the provincial government.

Taal has erupted 33 times since 1572.

The last eruption there in January 2020 shot ash 15km (9 miles) high and spewed red-hot lava, crushing scores of homes, killing livestock and sending more than 135,000 people into shelters.

Taal also has the distinction of being the only known volcano in the world within a lake on an island.

It is a popular tourist destination for its picturesque crater lake.
