Two volcanic earthquakes recorded at Kanlaon Volcano

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) on Saturday said two volcanic earthquakes occurred at Kanlaon Volcano in the past 24 hours.

The quakes were monitored from 12 a.m. Friday to 12 a.m. Saturday.

PHIVOLCS said 5,397 tonnes of sulfur dioxide were emitted on June 28, the highest emission of volcanic gas at Kanlaon Volcano since instrumental gas monitoring began.

The volcano which straddles Negros Occidental and Negros Oriental also emitted weak plumes rising up to 150 meters tall, according to PHIVOLCS' bulletin.

The plumes then drifted west-southwest and southwest.

PHIVOLCS said Kanlaon Volcano remains to be under Alert Level 2 which means increased unrest.

It reiterated that entry into the volcano's 4-kilometer radius permanent danger zone is prohibited.

Flying aircraft close to Kanlaon Volcano is also not allowed, PHIVOLCS added.

This is due the possible hazards that might occur, such as sudden steam-driven or phreatic eruptions.

Kanlaon volcano erupted last June 3, emitting plumes that rose to 5,000 meters. The eruption lasted 6 minutes and was followed by a relatively strong volcanic-tectonic earthquake. —KG, GMA Integrated News
