MANILA, Philippines – The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported only about 29 volcanic earthquakes around Taal Volcano in the past 24 hours, an indication that rocks underground are breaking.

A column of white steam also continues to form but only up to 50 meters in height.

It has been a week since PHIVOLCS downgraded alert level over the Taal volcano to level 2 from the previous level 3.

According to PHIVOLCS OIC Usec. Renato Solidum, they need to observe Taal volcano’s activities for one more week before they can decide whether to further downgrade the alert status based on the agency’s standard operating procedure.

“Basta tuloy-tuloy ang kanyang mga parametro na bumababa ang bilang pwede natin masabi na pwede nating ibaba ito sa alert level number one (If the parameters continue to reduce in number, we might lower the alert level to number one),” Solidum said.

Entry restrictions remain within the permanent danger zone in Taal Volcano Island.

Solidum said the local government unit needs to assess first if the former residential areas would be conducive for living.

PHIVOLCS does not recommended constructing houses on the volcano island due to the risk of having the ground break apart should the volcano proceed to erupt. MNP (with details from Rey Pelayo)

Phivolcs lowers alert status of Mayon Volcano to Alert Level 0

MANILA, Philippines—Alert status in Mayon Volcano was lowered to Alert Level 0 from Alert Level 1, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).

In an advisory, Phivolcs reported a decline in the frequency of volcanic earthquakes for the last six months. There is also a decreasing rate of inflation of the Mayon edifice this year. Sulfur Dioxide (SO2) emission flux from Mayon crater based on continuous gas spectrometry has declined below the baseline level of 500 tonnes per day since July 14.

Due to this, no magmatic eruption is foreseen in the immediate future, according to Phivolcs. However, there is still a possibility that alert level can be raised to Level 1 if there is a renewed increase of volcanic activity.

The public is still reminded to avoid entry into the 6-km Permanent Danger Zone or PDZ due to perennial hazards of rockfalls, avalanches, ash puffs and sudden steam-driven or phreatic eruption at the summit area which may occur without warning. AAC
