Taal Volcano’s seismic monitoring network recorded two (2) volcanic earthquakes during the past 24 hours. Field measurements conducted on 28 April 2016 at the eastern sector of the Main Crater Lake yielded a slight decrease in water temperature from 32.9°C to 32.6°C, a decrease in water level from 0.22 meter to 0.18 meter, and slight increase in acidity from pH 2.97 to 2.96. Ground deformation measurements through precise leveling survey from 28 March to 8 April 2016 indicated slight deflation of the edifice compared to November 2015 survey. Results from continuous GPS data as of 30 March 2016 showed deflationary trend since January 2016, however the edifice remains inflated relative to the 2014 baseline level. Carbon dioxide (CO2) emission at the Main Crater Lake decreased to 1380 tons/day in January 2016 from 1566 tons/day in October 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.
