Due to "increasing disturbances", the Philippine Institute of Volcanology and Seismology, Phivolcs, raised the alert level for the Taal volcano on Saturday. After the island's volcano spewed plumes and recorded earthquakes around 7:22 a.m. local time, the institute raised the volcano's alert level to 3 on a scale of 5.


The volcano in Batangas province, 66 kilometers south of Manila, “produced a short-lived phreatomagmatic explosion followed by nearly constant phreatomagmatic activity that generated plumes at 1,500 meters and volcanic earthquakes,” according to the institute. The institute warned that "magmatic intrusion" near the main crater "could further accelerate subsequent eruptions", and advised the public to avoid the volcanic island. He also advised against flying over the volcano.

Update : the alert level remain at 2, and Activity at the Main Crater was only dominated by the generation of plumes 1,200 meters tall that drifted southwest and west-southwest.

During the last 24 hours (as of May 07, 2022 / 05h), Phivolcs recorded 11 volcanic earthquakes in Kanlaon. The view of the volcano is obscured by clouds.

Sulfur dioxide emissions were 151 tonnes/day, measured on May 1, 2022.

A slight inflation marks the volcano.

The volcanic alert is at level 1, with prohibition to enter the danger zone with a radius of 4 km, and to fly over the zone, due to possible phreatic eruption.

The persistent rains in the surroundings of Fuego, generate moderate to strong lahars in the barranca Ceniza, tributary to the rio Achiguate and in the barranca Las Lajas tributary to the rio Guacalate; they consist of fine and hot volcanic materials and carry branches and trunks of trees, as well as blocks of 30 cm to 2 m. of diameter.

The volcanic deposits are saturated with water due to the showers of the previous days, and lahars can occur in the evening and during the night.

It is recommended to remain attentive to possible damage or interruptions in the passage of vehicles on the routes that connect the aforementioned municipalities. It is dangerous to attempt to cross or stay in these channels during the descent of the lahars.
