Intense earthquakes in Taal indicate possible ‘explosive eruption’ — PHIVOLCS

BATANGAS, Philippines – The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported intense seismic activity in Taal volcano in the past 24 hours.
As of Tuesday (January 14), the agency recorded a total of 212 volcanic earthquakes in the region of Taal, of which, 81 were felt with intensities ranging from Intensity I to V in the areas of Tagaytay City, Cavite.
“Such intense seismic activity probably signifies continuous magmatic intrusion beneath the Taal edifice, which may lead to further eruptive activity,” PHIVOLCS said in its report.
Based on PHIVOLCS’ 24-hour monitoring, Taal Volcano’s main crater has been continuously erupting due to magmatic and hydrovolcanic activity which generated 500-meter tall lava fountains and about two kilometers tall dark gray steam.
Since the last update, the agency said, heavy ash fall has reportedly fallen on the municipalities of Lemery, Talisay, Taal, and Cuenca, Batangas.
Sulfur dioxide emissions blanketed the air which were measured at an average of 5,299 tons per day on Monday (January 13).
PHIVOLCS maintains Alert Level 4 over Taal Volcano which means a possibility of a hazardous explosive eruption is high within hours to days.
Thus, the agency strongly reiterates total evacuation of the entire Taal Volcano Island as well as nearby areas at high risk to pyroclastic density currents and volcanic tsunami within a 14-kilometer radius from Taal’s main crater.
Communities north of Taal Volcano are advised to guard against the effects of heavy and prolonged ash fall.
PHIVOLCS remains in close monitoring of the activities of Taal Volcano and assures the public of up to date information.
In a press briefing on Tuesday, PHIVOLCS OIC Renato Solidum advised the public to be aware of the developments in Taal’s activities as major explosive eruption remains a possibility.
“We need the cooperation of everyone. The scenario of hazardous eruption is a real scenario that has been exhibited by Taal volcano. If we look at those scenarios, the impact is quite significant. Therefore, people need to be reminded that going inside the recommended evacuation zone is a risky business and in reality we need to focus on moving people away from identified areas,” he said.
“The mere fact that we are recording a lot of earthquakes and the fissures are now observed, meaning the entire area of Taal is being pushed by the magma intrusion, that would now be a possible source, if this would reached the surface, for a possible eruption and hopefully it’s not explosive but based on past events, it becomes explosive,” he concluded.
MANILA, Philippines – The Philippine Institute of Volcanology and Seismology (Phivolcs) on Thursday said it has downgraded the alert on Taal Volcano to level 1 following the decrease in volcanic quakes and surface activity at the main crater.
In its bulletin, Phivolcs said the Taal Volcano’s condition in the succeeding four weeks after its alert was lowered to level 2, has been characterized by low-level volcanic earthquake activity, stabilizing ground deformation of the Taal Caldera and the Taal Volcano Island edifices, and weak surface activity at the Main Crater and the Daang Kastila fissure.
“DOST-PHIVOLCS is lowering the alert status of Taal Volcano from Alert Level 2 to Alert Level 1 to reflect the overall decreasing trend in the level of monitoring parameters,” its bulletin reads.
State volcanologists said that alert level 1 means that the volcano is still in “abnormal condition,” and that this “should not be interpreted that unrest has ceased or that the threat of an eruption has disappeared.”
Under alert level 1, sudden steam-driven or phreatic explosions, volcanic earthquakes, minor ashfall and lethal accumulations or expulsions of volcanic gas can occur and threaten areas within the Taal Volcano Island.
The alert level may be raised back to alert level 2 “should pronounced change in monitored parameters forewarn of renewed unrest,” Phivolcs said.
The agency reminded residents that entry to Taal’s permanent danger zone, especially the vicinities of the Main Crater and the Daang Kastila fissure, remains strictly prohibited.
The Taal Volcano was placed under alert level 4 when it spewed ash on January 12 which sent thousands of residents to temporary shelters and disrupted businesses in surrounding areas.
It was later lowered to alert level 2 several weeks later due to decreased unrest. — ROBIE DE GUZMAN
MANILA, Philippines — Players from UNTV Cup – the Liga of Public Servants – are set to join the Wish Olympics, a charity sports and entertainment event for the benefit of the victims of the Taal Volcano eruption.
Among the players are PNP Responders’ Mariano “Neil Perez” Flormata Jr. and Anton Tolentino, Julius Casaysayan of Agriculture Food Masters, Rod William Vasallo of PITC Global Traders and Carlo Gonzalez of GSIS Furies.
PBA Legends and UNTV Cup Commissioners Atoy Co and Ed Cordero, as well as PBA Legends Allan Caidic, Johnny Abarrientos, Jayjay Helterbrand, Chris Calaguio, and Willie Miller, will also be gracing the event and extend their support.
Spearheaded by Wish 107.5 innovator and public service advocate, Kuya Daniel Razon, Wish Olympics will be held on February 23, 2020, at Smart-Araneta Coliseum.
It is aimed at extending more charity works to the people of Batangas, Cavite, and Laguna who have been severely affected by the explosion of the Taal Volcano.
Since the first week of the calamity, UNTV and the Members Church of God International, together with local and national government agencies have been carrying out medical missions and relief efforts for the victims.
Razon said he realizes the enormity of the eruption’s aftermath and that it will take months before the evacuees could carry on again with their normal lives.
This, he said, prompted him to think of ways to better extend assistance to the victims, and such is by way of the said sports and entertainment event.
It will be participated in by artists like Morisette, Imago, Clara Benin, Jayda, The Juans, The Wishfuls, Rhea Basco, Mark Herras, JayR, Rayver Cruz, Ejay Falcon, Young JV, Jordan Herrera, Adrian Alandy, James Blanco, Albie Casino, Gerhard Acao and Axel Torres.
Professional volleyball players and TV/movie personalities such as Gretchen Ho, Kathy Bersola, Claudia Barretto, Gwen Zamora, Roma Joy Doromal, Che Sindayen, Jem Ferrer, Patcharee Saengmuang, Sandy Delos Santos, Aya Fernandez, Casey Da Silva, Ana Gopico, Amanda Villanueva, Nicole Tiamzon, Heather Guino-o, and Erika Alkuino will also team up for a friendly volleyball match.
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)
