Negros oriental: Residents near Kanlaon Volcano, which spans the provinces of Negros Oriental and Negros Occidental, should not underestimate ashfall even if it appears light, the Philippine Institute of Volcanology and Seismology's (Phivolcs) chief said Tuesday. Phivolcs recorded ash emissions from the volcano's summit crater at around 5:32 a.m. and 6:01 a.m. Tuesday, generating grayish plumes that rose to 800 meters above the crater.

According to Philippines News Agency, Phivolcs Director Teresito Bacolcol stated that the ash emission is part of the volcano's current unrest. Bacolcol cautioned the public that ashfall should not be taken lightly, even if it appears light. He advised residents to "wear a mask, cover the food and drinking water, and wet the ash deposit before cleaning to prevent it from being airborne again."

Bacolcol emphasized the importance of avoiding the four-kilometer permanent danger zone and urged residents to heed advisories from local governments. He noted that ash emission and ashfall are possible in all active volcanoes, with the intensity depending on the volcano's current activity.

He drew parallels with Mayon Volcano in Albay, which has generated ash during lava flow or lava dome collapses, like the event on May 2. Bacolcol added that ash in both Mayon and Kanlaon volcanoes can also be produced through degassing and explosive eruptions.
