Six ash emission events that lasted for six to 20 minutes long were recorded at Kanlaon Volcano in a 24-hour period, the Philippine Institute of Volcanology and Seismology (Phivolcs) said yesterday.

The volcano on Negros Island also released 7,082 tons of sulfur dioxide flux on Saturday, November 16.

The emissions were from 12:00 a.m. on Saturday to 12:00 a.m. yesterday.

Kanlaon Volcano, which had continuous degassing, also discharged a “voluminous” 600-meter tall plume, drifting south and southeast.

Three volcanic earthquakes were also monitored at Kanlaon Volcano.

Phivolcs on November 15, posted time-lapse footage showing ash emissions from the Kanlaon Volcano summit crater that was observed between 8:45 a.m. and 10:02 a.m.

“These events generated grayish plumes that rose 350 meters above the crater before drifting west as recorded by the Kanlaon Volcano Observatory-Canlaon City IP cameras,” Phivolcs said.

Kanlaon Volcano has been observed to be degassing since October 19, and occasionally has weak ash emission from its summit crater.

Alert Level 2 is currently raised at Kanlaon Volcano due to “increased unrest” following its explosive eruption on June 3.

Entry into the volcano’s four-kilometer radius permanent danger zone and flying any aircraft close to it are prohibited.

Phivolcs warned that the volcano may have sudden steam-driven or phreatic eruptions, as well as precursory magmatic activity. (GMA Integrated News)
