Taal Volcano’s (14.0000°N, 120.9833°E) seismic network did not record any volcanic earthquake during the past 24-hour observation period. Field measurements conducted last May 25 at the eastern sector of the Main Crater Lake yielded a slight decrease in water temperature of 33.9°C from 34.1°C, and decreased water level of 0.16 meter from 0.21 meter. Ground deformation survey (precise leveling) on the Volcano Island last 15 - 17 February 2012 indicated no significant change compared with October 2011, but is nonetheless still inflated compared with baseline data. GPS data for the period of February 2011 to second week of March 2012 show steady deflation beginning in August 2011, but nonetheless also indicated that the edifice is still slightly inflated compared to February 2011 baseline data.
