Based on the latest bulletin, a series of five phreatomagmatic bursts occurred at 8:47 a.m., 9:15 a.m., 9:26 a.m., 11:56 a.m., and 9:41 p.m. on Wednesday, July 7.
The phreatomagmatic explosions produced “short-jetted” plumes that rose up to 700 meters above the Taal’s main crater lake.In the past 24-hour period, Phivolcs recorded 60 volcanic earthquakes, including five explosion-type quakes, 24 low frequency volcanic quakes, 21 volcanic tremor events with durations between two to four minutes, 10 hybrid earthquakes, and low-level background tremor on Wednesday.
State volcanologists also measured high levels of volcanic sulfur dioxide gas emissions and steam-rich plumes at Taal’s main crater which rose 1,500 meters before drifting southwest.“At Alert Level 3, magma extruding from the main crater could drive explosive eruption,” Phivolcs said. It reminded the public that the entire Taal Volcano Island is a Permanent Danger Zone , 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 occurCommunities around the Taal Lake shores were also advised to remain vigilant, as well as take precautionary measures against possible airborne ash and volcanic smog or “vog” and calmly prepare for...
“Civil aviation authorities must advise pilots to avoid flying over Taal Volcano Island as airborne ash and ballistic fragments from sudden explosions and pyroclastic density currents such as base surges may pose hazards to aircraft,” Phivolcs said.
