Taal volcano news & activity updates

Taal volcano (Luzon, Philippines) activity update: signs of 2011 unrest - increased water temperature, inflation - ceased

The water of the Taal caldera lake has become cooler and less acidic and GPS measurements have been showing deflation since August of 2011. This suggests that the unrest at Taal in 2011 was likely an intrusion that has since ceased, the Eruptions Blog writes.
However, PHILVOLCS maintains the alert level at 1, because the edifice is still slightly inflated compared to February 2011 and CO2 emission are still elevated. At the Main Crater Lake 627 tonnes per day were measured on 07 July 2012 compared to 482 tonnes per day last 18 October 2011. PHILVOLCS advises that that the Main Crater should be strictly off-limits because sudden steam explosions may occur and high concentrations of toxic gases may accumulate there.

Field measurements on 21 February 2012 at the western sector of the Main Crater Lake yielded slight increase in water temperature of 31.8°C from 31.4°C, decrease in water level of 0.65 meter from 0.72 meter and slight increase in acidity of pH 2.82 from pH 2.86. 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 to first week of November 2011 showed slight deflation in Taal Volcano Island beginning August, but nonetheless also indicate that the edifice is still slightly inflated compared to February baseline data. read all
