Taal spews thick vapor again; number of quakes increasing

Taal Valcano

Restive Taal Volcano sprayed a large column of dense, white steam early Friday morning, suggesting that underneath the crater heating of volcanic materials has increased.

Restive Taal Volcano sprayed a tall column of high, white steam early Friday morning, suggesting that underneath the crater heating of volcanic materials has accelerated.

The steam recorded at 6 a.m., Reniva said, too. It was low Thursday, less dense compared to this Friday morning’s steaming activity, which is much denser and higher.

On the other hand, Andal announced that as of Friday morning the number of volcanic quakes had increased to 466, from last Thursday’s 444. But none of those quakes, except instruments, were felt.

Experts from the Philippine Institute of Volcanology and Seismology (PHIVOLCS), however, said the high frequency of volcanic quakes indicates that magma is still on the move.

PHIVOLCS Early Friday’s Taal newsletter indicates that the main crater has been characterized in the last 24 hours by “low to moderate emissions of white steam-laden feathers 50 to 500 meters high.” Also, emissions of sulfur dioxide (SO2) have risen from 144 tons per day on Thursday to an average of 224 tons per day this Friday.

Alert Level 4 is still in place over Taal Volcano, PHIVOLCS said, adding that a dangerous explosive eruption within hours to days is likely.

It reiterates that Taal Volcano Island’s complete evacuation and high-risk areas are still in place as defined in the danger maps within the 14-km radius from the maid crater and along the Pansipit River Valley where fissuring has been observed.
