In the latest report from the Philippine Institute of Volcanology and Seismology (PHIVOLCS-DOST), it has been recorded that Taal Volcano experienced one volcanic earthquake and one volcanic tremor, which have been ongoing since June 2. These events have resulted in a release of 5,718 tons of Sulfur Dioxide Flux. Additionally, there has been an upwelling of hot volcanic fluids in the Main Crater Lake, causing the presence of VOG.
Furthermore, a strong eruption column measuring 2,400 meters in height was observed, drifting towards the west. Temporary swelling of the western part of Taal Volcano Island and a sustained depression of the larger Taal Caldera have also been noted.
The public is advised to remain cautious of the harmful effects of the smog and to strictly adhere to the protocols set by the authorities.
Moving on to Mayon Volcano, here is a summary of the observations made in the past 24 hours, from 5 AM yesterday to 5 AM today, June 8, 2023.
Mayon Volcano is currently experiencing increased unrest, prompting authorities to raise the alert level to 2. The following parameters were observed:
• Seismicity: 98 rockfall events lasting 2-3 minutes each.
• Crater glow: No glow observed.
• SO2 Sulfur Dioxide Flux: 332 tonnes per day as of June 7, 2023.
• Plume: A plume measuring 500 meters in height with moderate emissions, drifting generally towards the south.
• Ground Deformation: The volcano edifice is showing signs of inflation.
Regarding earthquake activity, no volcanic earthquakes were recorded in the past 24 hours, and there were no earthquakes with sufficient records for location in the past two weeks.
As a precautionary measure, entry into the 6-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited, and flying any aircraft near the volcano is not allowed.
The public is reminded of the potential hazards that may occur, such as sudden steam-driven or phreatic eruptions, rockfalls or landslides/avalanches, and lahars during heavy and prolonged rainfall.
