Taal Volcano’s seismic monitoring network recorded fifty-three (53) volcanic earthquakes during the 24-hour observation period. Two (2) of these were felt events in the volcano island. The first event occurred at 10:59 AM yesterday was felt at Intensity I by residents in Brgy. Calauit, Balete, Batangas. The second event occurred at 8:04 PM yesterday was felt at Intensity I with rumbling sound by residents in Brgy. Calauit, Balete, Batangas and Brgy. Pira-piraso, Talisay, Batangas. Field measurements on 02 January 2020 at the eastern sector of the Main Crater Lake yielded a decrease in water temperature from 31.6°C to 31.5°C, a decrease in water level from 0.34 meters to 0.27 meters, and an increase in acidity from a pH of 2.81 to 2.75. Ground deformation measurements through precise leveling surveys from 21 - 29 November 2019 indicated inflation of the edifice consistent with recent results from continuous GPS data.

Alert Level 1 remains in effect over Taal Volcano. This means that hazardous eruption is not imminent. The public, however, is reminded that the Main Crater should be strictly off-limits because sudden steam explosions may occur and high concentrations of toxic gases may accumulate. The northern portion of the Main Crater rim, in the vicinity of Daang Kastila Trail, may also become hazardous when steam emission along existing fissures suddenly increases. Furthermore, the public is also reminded that the entire Volcano Island is a Permanent Danger Zone (PDZ), and permanent settlement in the island is strongly not recommended.
