Taal remained under the third highest alert on Monday, as state volcanologists continued to record volcanic earthquakes and sulfur dioxide emission.
One of the 17 earthquakes lasted 45 minutes while the rest were low-frequency tremors, Phivolcs said. This means that "anytime soon," Taal could emit steam and gas like it did on July 1, Phivolc said.
Alert Level 3, or magmatic unrest, means that molten rocks or magma near the crater could lead to an explosive eruption.
On Sunday, the volcano emitted a record 22,628 tons of sulfur dioxide. Gas emissions and steam plumes rose as high as 2.5 kilometers on the same day.
Residents living near the caldera are barred from the Taal Volcano Island, a permanent danger zone, and high-risk barangays of Agoncillo and Laurel due to possible volcanic tsunami should the volcano erupt.
