MANILA, Philippines - The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded at least seven volcanic earthquakes around Taal volcano while one rock fall event was observed at Mayon volcano in the past 24 hours.
In Taal, the agency also noted an increase in water temperature at the eastern part of the main crater lake last Aug. 21.
But Phivolcs yesterday said alert level 1 remains in effect over Taal volcano, meaning a hazardous eruption is not imminent.
Phivolcs continued to remind the public that the main crater remains “strictly off-limits” because sudden steam explosions may occur and high concentrations of toxic gases may accumulate.
It added that the northern portion of the main crater rim, in the vicinity of Daang Kastila Trail, could also become dangerous when steam emission along existing fissures suddenly increases.
Phivolcs said the entire volcano island is a permanent danger zone and not for permanent settlement.
Meanwhile, aside from one rock fall event, Phivolcs also recorded a moderate emission of white steam plumes at Mayon volcano.
