TAAL VOLCANO BULLETIN 31 August 2015 8:00 A.M.

Taal Volcano’s seismic monitoring network recorded two (2) volcanic earthquakes during the past 24 hours. Field measurements conducted on 27 August 2015 at the western sector of the Main Crater Lake yielded a decrease in water temperature from 33.3°C to 33.1°C, an increase in water level from 0.32 to 0.49 meter, and a decrease in acidity from pH 3.08 to 3.18.

Ground deformation measurements through precise leveling surveys on May 25 to June 3, 2015 indicated slight inflation of the edifice compared to February – March 2015. Ground deformation measurements from GPS data also indicate an inflationary trend since May 2014, with the edifice being slightly inflated compared to February 2011 baseline data. Carbon dioxide (CO2) emission at the Main Crater Lake increased from 1634 tonnes/day in April 2015 to 2300 tonnes/day in July 2015.

Alert Level 1 remains in effect over Taal Volcano.
