Kanlaon Volcano, located within the boundaries of Negros Occidental and Negros Oriental, erupted on Monday evening, June 3.

The explosive eruption occurred at Kanlaon’s summit vent at 6:51 p.m. and lasted for six minutes, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS).

It “produced a voluminous and incandescent plume that rapidly rose to 5,000 meters above the vent and probable short pyroclastic density currents approximately two to three kilometers down the southern and southeastern slopes.”

At 8 p.m., PHIVOLCS  raised the alert status of Kanlaon to Level 2, which  means “there is current unrest driven by shallow magmatic processes that could eventually lead to further explosive eruptions or even precede hazardous magmatic eruption.”

The eruption was preceded by a “relatively strong volcano-tectonic earthquake.”

“PHIVOLCS maintains close monitoring of Kanlaon Volcano, and any new development will be communicated to all concerned stakeholders,” the agency said.

Kanlaon is one of the most active volcanoes in the Philippines. It has at least two craters: Lugad and Southern Crater.IMT
