Quake rocks Kanlaon again

Earthquakes are on the rise again at Kanlaon Volcano, the Philippine Institute of Volcanology and Seismology reported at 8 a.m. yesterday.

Seismic monitoring of Kanlaon Volcano recorded 197 volcanic earthquakes, 195 of which were micro earthquakes with 14 episodes of tremors lasting 2 to 30 minutes during the past 24 hours, Phivolcs said.

Moderate emission of white steam-laden plumes that drifted to the west was observed during times when the crater was visible, it also said.

Ground deformation data from continuous GPS measurements indicate slight inflation of the edifice since December 2015. Sulfur dioxide (SO2) emission was measured at an average of 640 tons a day on Jan. 3, Phivolcs added.

Alert Level 2 status prevails over Kanlaon Volcano, which means that the volcano is undergoing a moderate level of unrest.

There is probable intrusion of magma at depth which may, or may not lead to a magmatic eruption, it said.

The local government units and the public are reminded that entry into the 4-kilometer radius Permanent Danger Zone (PDZ) is strictly prohibited due to the further possibilities of sudden and hazardous steam-driven or phreatic eruptions, Phivolcs said.

Civil aviation authorities must also advise pilots to avoid flying close to the volcano's summit as a sudden phreatic eruption can be hazardous to aircraft, it added.*CPG
