TAAL VOLCANO BULLETIN 10 March 2016 8:00 A.M. PDF Print

Taal Volcano’s seismic monitoring network recorded did not detect any volcanic earthquake during the past 24 hours. Field measurements conducted on 03 March 2016 at the eastern sector of the Main Crater Lake yielded a slight decrease in water temperature from 30.6°C to 30.5°C, a decrease in water level from 0.47 meter to 0.40 meter, and a decrease in acidity from pH 2.70 to 3.07. 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 February 26, 2016 indicated an inflationary trend since July 2014. 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.
