ALERT LEVEL 1 (abnormal) status remained in effect as of Sunday’s update by Phivolcs, saying this meant it was in “a state of unrest probably driven by hydrothermal processes that could generate steam-driven or phreatic eruptions.” The update also read: “Local government units and the public are reminded that entry into the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited and that vigilance in the Extended Danger Zone (EDZ) must be exercised due to the increased possibilities of sudden and hazardous phreatic eruptions.”
