TAAL Volcano has another short-lived phreatomagmatic (combination of magma and water) eruption in its main crater on Wednesday, raising its explosions to five, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).

The fifth burst at 11:56 a.m. lasted for less than a minute and generated a 200-meter dark gray plume, according to Phivolcs chief Renato Solidum Jr.

He said the first explosion that took place at 5:18 a.m. lasted only for one minute and has generated a grayish plume that rose 300 meters before drifting southeast.

At 8:47 a.m., another burst took place for seven minutes and also generated a 300 meter-high plume, he said.

Solidum said there were two other phreatomagmatic events that happened 9:15 a.m. and 9:26 a.m. and lasted for two minutes and five minutes, respectively.

In the past 24 hours, the Taal Volcano Network (TVN) recorded 55 volcanic earthquakes, including an explosion-type earthquake, 44 low frequency volcanic earthquakes, five volcanic tremor events having durations of two to five minutes, five hybrid earthquakes and low-level background tremor.

The Phivolcs official said the volcano continues to emit high levels of volcanic sulfur dioxide or SO2 and steam-rich plumes 1,500 meters high before drifting southwest.

On July 6, some 7, 560 tons of SO2 were emitted by the volcano which remains under Alert Level 3, he said.

He said the entire Taal Volcano Island is a permanent danger zone and entry into the island as well as into the high-risk villages of the towns of Agoncillo and Laurel is prohibited due to the expected pyroclastic density currents and volcanic tsunami should strong eruptions occur.

"All activities on Taal Lake should not be allowed at this time and communities around the Taal Lake shores are advised to remain vigilant and take precautionary measures against possible airborne ash and vog," he said.

Solidum said that "based on parameters monitored, there is no downtrend yet".

"Stand down procedure or lowering of alert status that is being followed is two weeks of continuous downtrends," he said.

With the continued high emission of SO2 and recording of volcanic earthquakes, there remains the possibility of another eruption though it would not be as explosive as last year, Solidum said.
