Taal Volcano’s seismic monitoring network recorded thirty-six (36) volcanic earthquakes during the 24-hour observation period. Three (3) of these were felt events. The earthquake that occurred at 8:02 PM (last night) was felt at intensity II with rumbling sound by residents in Brgy. Alas-as, San Nicolas, Batangas. Two (2) earthquakes that occurred at 9:48 PM and 10:57 PM (last night), were felt at intensity I with rumbling sound in Barangay Alas-as, San Nicolas, Batangas. Field measurements on 07 November 2019 at the eastern sector of the Main Crater Lake yielded a decrease in water temperature from 33.0°C to 32.8°C, an increase in water level from 0.46 meters to 0.49 meters and an increase in acidity from a pH of 2.93 to 2.85. Ground deformation measurements through precise leveling surveys from 19 - 26 September 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.
