Kanlaon Volcano had 37 volcanic earthquakes in the past 24 hours, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said on Monday.
The volcano, straddling the provinces of Negros Occidental and Negros Oriental, also emitted 3,639 tonnes of sulfur dioxide on Sunday.
Voluminous plumes rising up to 500 meters tall were observed, indicating continued degassing. The plumes drifted in the southwest and west direction.
PHIVOLCS said Kanlaon Volcano’s edifice remains inflated.
Alert Level 3 (Intensified Unrest/Magmatic Unrest) remains in effect at Kanlaon Volcano.
PHIVOLCS said the six-kilometer radius from the volcano’s summit should be evacuated.
Flying any aircraft close to the volcano is not allowed, it added.
At Alert Level 3, Kanlaon Volcano may pose hazards such as sudden explosive eruption, lava flow or effusion, ashfall, pyroclastic density current or PDC, rockfall or lahars during heavy rains, PHIVOLCS said.
Kanlaon Volcano had an explosive eruption on December 9, prompting PHIVOLCS to raise the Alert Level from 2 to 3.
It also erupted on June 3, emitting 5,000-meter tall plumes. —KG, GMA Integrated News
