Kanlaon Volcano may getting restive, as the Philippine Institute of Volcanology and Seismology (Phivolcs) recorded at least 37 volcanic quakes over five days from the volcano area as of Sunday morning.

The volcano bulletin page of Phivolcs showed that it recorded seven volcanic quakes over a 24-hour period on Saturday. This was preceded by 12 volcanic quakes on Friday, 11 Thursday, two on Wednesday and five on Tuesday.

On Monday and Sunday, the agency did not record any volcanic quakes from Kanlaon.

Phivolcs also observed from Kanlaon Volcano “moderate emission of white steam-laden plumes that rose 500 meters before drifting southeast and northwest was observed. Sulfur dioxide (SO2) emission was measured at an average of 1,130 tonnes/day on 13 February 2021.” 

With Phivolcs recording 37 volcanic quakes from Kanlaon over four days, the agency is maintaining Alert Level 1 over the volcano area.

“DOST (Department of Science and Technology)-Phivolcs would like to remind the public that Kanlaon Volcano is at Alert Level 1, which means that it is at an abnormal condition and has entered a period of unrest. The local government units and the public are strongly reminded that entry into the 4-kilometer radius Permanent Danger Zone (PDZ) must be strictly prohibited due to the further possibilities of sudden and hazardous steam-driven or phreatic eruptions.”

“Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as ejecta from any sudden phreatic eruption can be hazardous to aircraft. DOST-Phivolcs is closely monitoring Kanlaon Volcano’s activity and any new development will be relayed to all concerned,” it added. SOVEREIGNPH
