MANILA, Philippines — The Philippine Institute of Volcanology and Seismology (Phivolcs) on Wednesday (March 24) warned about an increasing possibility of a magmatic eruption in Taal Volcano following an elevated increase in seismic activity.

In an advisory, Phivolcs said that since the Taal Volcano unrest in February, the overall volcanic activity has increased. The agency has recorded 259 volcanic earthquakes in Taal Volcano in the past 24 hours.

In the previous week, sulfur oxide gas emission also reached a high peak compared to the previous month. 

There has also been an indication of magma migrating across shallow depths of the Taal Volcano island which increased the possibilities of a magmatic eruption, according to Phivolcs.

“Alert Level 2 (increased unrest) is currently maintained over Taal Volcano but that unrest has been elevating and is under constant evaluation,” according to Phivolcs.

The agency maintains an Alert Level 2 in Taal. It also reminds local government units to continuously assess and strengthen their preparation. Entry is prohibited on the Taal Volcano Island, Taal’s permanent danger zone, especially the vicinity of the main crater and the Daang Kastila fissure. -AAC

Phivolcs to launch mobile app for volcano information

Aileen Cerrudo   •   June 17, 2021

MANILA, Philippines — The Philippine Institute of Volcanology and Seismology (Phivolcs) will launch a mobile app on Monday (June 21) to make the current status of volcanoes easily available to the public.

On Thursday (June 17), Phivolcs announced that the “VolcanoPH Info” app will be available on Android devices. Through the app, the public can access the latest volcano bulletins and advisories.

The app will help users understand the current volcano status, and more importantly, identify the necessary preparedness and response actions for their safety.

“We aim to provide the users with accessible and easy-to-read information,” said DOST Undersecretary and Phivolcs Officer-in-Charge Renato Solidum Jr.

Once a user is able to access the app, he or she can select from the list of volcanoes with alert levels on the homepage.

The selection will provide the user with a summary of the 24-hour observation period containing the alert level, monitoring parameters, and recommendations in the Filipino language.

Future developments of the app include the English language setting and iOS version. AAC

Hirap sa paghinga dulot ng asupre, nararanasan sa Agoncillo, Batangas

BATANGAS  —  Karamihan sa mga residente ay nananatili na lang muna sa loob ng bahay upang maiwasan nila ang amoy ng asupre na ibinubuga ng Bulkang Taal.

Isa na diyan si Nanay Elsa na nakaranas ng paninikip ng dibdib at hirap sa paghinga. Ayon kay Nanay Elsa nakararanas din sila ng pananakit ng lalamunan kapag nakakalanghap sila ng asupre.

Kaya naman madalas na silang nakasuot ng facemask lalo na kung hindi maiiwasang lumabas ng bahay.

“Parang may naamoy akong hindi maganda at parang sumikip ang dibdib ko ako naman bakit ganito sumikip ang dibdib ko mahirap huminga po para akong nahilo ako’y inubo na,” aniya.

Bukod sa mga residente na apektado ng asupre sa Barangay Banyaga, Bilibinwang at Subic Ilaya ay apektado na rin ang kanilang mga pananim at mga halaman na natutuyo dahil sa asupre.

Paliwanag naman ng Philippine Institute of Volcanology and Seismology (PHIVOLCS), ang pagbuga ng sulphur dioxide ay nagpapakita na nasa mababaw na bahagi ng bulkan ang magma.

Bunsod nito, patuloy na pinag-iingat ng PHIVOLCS ang mga residente sa paligid ng bulkan at dapat anilang laging nakahanda ang mga opisyal ng lokal na pamahalaan.

Nananatiling nasa Alert Level 2 ang bulkan at posible pa ring mgakaroon ng steam-driven o phreatic explosion ayon sa PHIVOLCS.

Taal recorded 221 volcanic earthquakes in the past 24 hours — Phivolcs

MANILA, Philippines — The Philippine Institute of Volcanology and Seismology (Phivolcs) on Tuesday (June 15) recorded a total of 221 volcanic earthquakes in Taal Volcano in the past 24 hours.

According to their latest bulletin, Phivolcs recorded 29 low-frequency tremors out of the 221, while 192 volcanic tremors occurred with durations from one to 135 minutes.

There was also an upwelling of hot volcanic fluids which resulted in plumes reaching 1,500 meters tall, drifting southwest.

As of June 14, sulfur dioxide (SO2) emissions averaged 5,837 tonnes per day.

The agency previously warned residents near Taal Volcano, particularly in Agoncillo, Batangas, to wear face masks and to stay hydrated to prevent inhaling sulfur oxide.

Meanwhile, Phivolcs stated that due to the ground deformation parameters from electronic tilt, Taal Volcano Island has begun deflating in April 2021.

“The Taal region continues to undergo very slow extension since 2020. These parameters indicate overall that magmatic unrest continues to occur at shallow depths beneath the edifice,” the bulletin stated.

Alert Level 2 is still raised in the region where Phivolcs strongly recommends that entry must be strictly prohibited into Taal Volcano Island, Taal’s Permanent Danger Zone, or PDZ, especially the vicinities of the Main Crater and the Daang Kastila fissure, and occupancy and boating on Taal Lake.
