Renato Solidum, chief of the Philippine Institute of Volcanology and Seismology (Phivolcs), told The Manila Times that Alert Level 2, which means increased unrest, is currently up over Taal Volcano. “But elevated unrest has recurred in the past 48 hours and volcano conditions remain unstable,” he said. The Phivolcs chief said there is elevated unrest if some monitored parameters like volcano seismicity or earthquakes and gas emission are showing high values. In the past 24 hours, the Taal Volcano Network (TVN) recorded 355 volcanic earthquakes, of which 201 were low frequency, and 154 tremors with durations ranging from two to 35 minutes. Some 3, 463 tons of sulfur dioxide were also emitted by the volcano, Phivolcs said.
