MANILA, Philippines – The Philippine Institute of Volcanology and Seismology (PHIVOLCS) has lowered the alert status of Taal Volcano to level 1 on Tuesday morning.

In a statement, PHIVOLCS said that a "large hazardous eruption" is now less probable after its seismic activity has declined since June 2011.

PHIVOLCS said that since June 6, zero to 6 small seismic events have been recorded daily from the volcano. It added that no perceptible volcanic earthquake has occurred since June 2.

Meanwhile, hydrothermal and steaming activities in the northern and northeast sides of the main crater and Daang Kastila trail area have also abated, PHIVOLCS said.

Carbon Dioxide (CO2) gas measurements at the Main Crater Lake since March 2011 also showed a decreasing trend.

The agency, however, is reminding the public that the main crater will remain strictly off-limits because sudden steam explosions may occur and high concentrations of toxic gases may accumulate.

PHIVOLCS added that the entire Volcano Island is a Permanent Danger Zone (PDZ), and permanent settlement in the island is discouraged.
