Taal Volcano’s seismic monitoring network did not detect any volcanic earthquake during the past 24 hours. Field measurements on 28 January 2016 at the western sector of the Main Crater Lake yielded a slight decrease in water temperature from 30.9°C to 30.2°C, a slight decrease in water level from 0.63 meter to 0.55 meter, and slight decrease in acidity from pH 2.90 to 3.01.   Ground deformation measurements through precise leveling surveys from November 3 to 16, 2015 indicated very slight deflation of the edifice compared to September-October survey. However, ground deformation from continuous GPS data as of Jan 27, 2016 indicated an inflationary trend since July 2014. 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.
