Taal eruption not imminent despite 10 volcanic earthquakes observed in 24-hour period

The Philippine Institute of Volcanology and Seismology (Phivolcs) has recorded 10 volcanic earthquakes during the 24-hour observation of Taal Volcano in Batangas.

Likewise, based on Phivolcs’ field measurements since April 11, the eastern sector of Taal Volcano’s main crater lake yielded an increase in water temperature from 31.7 degrees Celsius (°C) to 31.9 °C, a decrease in water level from 0.41 meter to 0.31 meter and increase in acidity from pH 2.67 to pH 2.95.

It also measured ground deformation through precise leveling surveys from March 18 to 27, which indicated slight inflation of the edifice consistent with recent results from continuous GPS data.

Taal Volcano’s alert status remains at level one due to the abnormal condition of the volcano.

It has been raised from zero to one last March 28.

However, Phivolcs clarified that alert level one means “hazardous eruption is not imminent.”

The public meanwhile is reminded that the main crater should be strictly off-limits because sudden steam explosions can occur and high concentrations of toxic volcanic gases can be released.

The northern portion of the main crater rim, in the vicinity of Daang Kastila Trail, can also become hazardous when fumarolic or degassing activity along existing fissures suddenly increases.

Furthermore, the public is also reminded that the entire volcano island is a permanent danger zone and permanent settlement is strictly prohibited.
