00 volcano icon for bulletin Taal Volcano’s seismic monitoring network recorded eleven (11) volcanic earthquakes during the past 24 hours. Field measurements on 18 April 2019 at the western sector of the Main Crater Lake yielded an increase in water temperature from 31.3°C to 32.8°C, a decrease in water level from 0.34 meter to 0.25 meter and decrease in acidity from pH 2.85 to pH 2.98. Ground deformation measurements through precise leveling surveys from March 18 to 27, 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.
