On July 1, 2021, at 07:16 UTC (15:16 LT), a phreatic eruption occurred on Taal Volcano, Philippines, resulting in a dark plume of ash up to 1 km high.
In connection with the above, DOST-PHIVOLCS raised the alarm status from alarm level 2 to 3.
"This means that magmatic intrusion is taking place in the Main Crater, which could lead to subsequent eruptions," PHIVOLCS said.
Taal is an active volcano in the Philippines and a popular tourist attraction in the country. Located on the island of Luzon, 50 km south of the capital of the Philippines, Manila. The volcano is a large caldera filled with Lake Taal.
The Agency strongly recommends evacuating from the Taal volcano island and from the Agoncillo and Laurel, Batangas areas, due to the possible danger of pyroclastic flows and volcanic tsunami.
“We remind the population that the entire Volcano Island is a Permanent Hazard Zone (PZZ), and entry to the island, as well as to the high-risk areas of Agoncillo and Laurel, is prohibited.
In addition, residents of the coastal areas of Lake Taal are advised to take precautions and be vigilant about possible water fluctuations in the lake caused by ongoing eruptions."
High levels of volcanic sulfur dioxide or SO2 gas emissions and high, steam-rich plumes have been observed over Taal Main Crater since last weekend, PHIVOLCS reported on Tuesday, June 29, 2021.
SO2 emissions averaged 14,326 tonnes per day on 28 June 2021, the highest in Taal's history.
On June 29, DOST-PHIVOLCS reported adverse impacts on some residents of the Lake Tanaouan City and Talisay Municipality facing the Taal Volcano Island, as well as some fish aquaculture workers in Lake Taal.
