As usual, Alert Level 4 is still hoisted over the volcano. This means that hazardous explosive eruption is possible within hours to days.

The institute reiterated the total evacuation of Taal Volcano Island and high-risk areas as identified in the hazard maps within the 14-km radius from Taal Main Crater and along the Pansipit River Valley where fissuring has been observed.
