MANILA -- Government seismologists said Sunday that five volcanic earthquakes were felt during the past 25 hours near Taal Volcano.

Water temperature at the volcano's Main Crate Lake also increased from 31.8 degrees Celsius to 32.0 degrees Celsius, while the pH value became more slightly acidic, said the Philippine Institute of Volcanology and Seismology (Phivolcs).

It was also observed that Taal's edifice remains inflated.

With this, the Phivolcs announced that alert level 2 is still in effect over Taal. This alert level status means that "magma has been intruding toward the surface, as manifested by the continuing high emission rate of CO2 being released in the Main Crater Lake and sustained seismic activity."

Phivolcs advised the public not to go near the Main Crater, Daang Kastila Trail and Mt. Tabaro as "sudden hazardous steam-driven explosions may occur and high concentrations of toxic gases may accumulate."

Breathing air with high concentration of toxic gases can be lethal to human, animals and even cause damage to vegetation, it said.

Phivolcs also reminded the public that the entire Volcano Island is a Permanent Danger Zone, and permanent settlement in the island is strictly not recommended.

The agency assured that it is closely monitoring Taal's activity. (Sunnex)
