Taal Volcano’s seismic monitoring network recorded three (3) volcanic earthquakes during the past 24 hours. Field measurements conducted on 19 November 2015 at the western sector of the Main Crater Lake yielded a decrease in water temperature to 32.3°C from 32.8°C, a decrease in water level to 0.62 meter from 0.67 meter, and an increase in acidity to 2.80 from pH 3.13. Ground deformation measurements through precise leveling surveys from November 3 to 16, 2015 indicated very slight deflation of the edifice compared to September 21 to October 1, 2015, consistent with slight deflation recorded by continuous GPS since September 2015. However, both consistently show a general inflationary trend since January 2015. Carbon dioxide (CO2) emission at the Main Crater Lake decreased to 1566 tons/day in October 2015 from 2300 tons/day in July 2015.

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.
