1,007 volcanic quakes in past 24 hours at Kanlaon volcano
For the past 24 hours- from 8 a.m. December 13 to 8 a.m. Dec. 14, there were 1,007 volcanic earthquakes recorded at Mt. Kanlaon.
In the 8 a.m. Dec. 14 Kanlaon Volcano Bulletin of the Philippine Institute of Volcanology and Seismology (Phivolcs), Kanlaon’s seismic monitoring network recorded one thousand and seven (1,007) volcanic earthquakes during the past 24 hours.
“Moderate emission of white steam-laden plumes that rose to 300 meters before drifting southwest was observed. 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 687 tonnes/day on December 13, 2017,” it said.
“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. The local government units and the public are strictly 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 report indicated.
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, Phivolcs added.
Local government units in cities and towns near the volcano are on alert for any eventuality, the Negros Occidental Provincial Government meanwhile reported yesterday.*(Arman P. Toga)
