00 volcano icon for bulletin Taal Volcano’s seismic monitoring network recorded twenty-eight (28) volcanic earthquakes during the 24-hour observation period. One of these earthquakes, which occurred at 9:40AM yesterday, was felt at Intensity I with rumbling sound at the Main Crater Lake. Field measurements on 19 September 2019 at the western sector of the Main Crater Lake yielded an increase in water level, from 0.39 meters to 0.49 meters. Ground deformation measurements through precise leveling surveys from 15 – 24 June 2019 indicated slight 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.
