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

MANILA, Philippines—More volcanic earthquakes were recorded in Taal Volcano, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).

Based on the latest bulletin, 185 volcanic earthquakes were recorded during the 24-hour period, including seven low frequency volcanic earthquakes, 176 volcanic tremor events having durations of one to 16 minutes. High levels of volcanic sulfur dioxide (SO2) gas emissions averaging to 6,421 tonnes per day were also recorded on July 11. Steam-rich plumes that rose 1,500 meters before drifting southwest and west-northwest were also generated from the Taal Main Crater.

Alert Level 3 is still maintained over Taal Volcano. The public is reminded that the entire Taal Volcano Island is a Permanent Danger Zone (PDZ), and entry into the island as well as into the high-risk barangays of Agoncillo and Laurel must be prohibited due to the hazards of pyroclastic density currents and volcanic tsunami should strong eruptions occur. Civil aviation authorities must advise pilots to avoid flying over Taal Volcano Island.

“All activities on Taal Lake should not be allowed at this time. Communities around the Taal Lake shores are advised to remain vigilant, take precautionary measures against possible airborne ash and vog and calmly prepare for possible evacuation should unrest intensify,” according to Phivolcs.

The agency also assured it continues to closely monitor the volcanic activities in Taal. AAC
