On 15 November 2017, Kanlaon Volcano's seismic monitoring network recorded two hundred seventy nine (279) deep volcanic earthquakes. Since 18 August 2017, the number of volcanic earthquakes detected per day has continued to increase. There has been no visible degassing or steaming from the active vent this year, although increased unrest could possibly develop into steam-driven or phreatic eruptions at the summit.

Kanlaon Volcano’s seismic monitoring network recorded 578 volcanic earthquakes during the past 24 hours. Moderate emission of white steam-laden plumes that rose to 800 meters before drifting northwest was observed.
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. 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.

Kanlaon Volcano in Negros has remained restive as the Philippine Institute of Volcanology and Seismology (Phivolcs) recorded 155 new volcanic earthquakes over the past 24 hours.

The agency’s seismic monitoring network on Monday reported that the active volcano moderately emitted white steam-laden plumes with height of 1,000 meters before drifting southwest.

Slight inflation of the edifice of the volcano since December 2005 was still noted through the ground deformation data from continuous global positioning system measurements, the monitoring network report said.

On Saturday, Phivolcs recorded a low-energy phreatic eruption. It was an explosion-type earthquake that lasted for about 10 minutes.

The event ejected dark ash and voluminous steam at three to four kilometers above the summit vent. It was accompanied by a rumbling sound heard by residents of La Castellana, Negros Occidental.

Degassing at the summit was also observed and detected through continuous low-energy tremor during periods when the summit was not visible.

As this developed, the Bago City Disaster Risk Reduction and Management Office and City Health Office implemented Rapid Damage Assessment and Needs Analysis in Barangay Ilijan on Sunday.

The team conducted ocular inspection, including interviews with the affected community. The city’s Health Emergency Management Staff also distributed masks to residents in the area.

Amid the recent activities, Alert Level 2 status still prevails over Kanlaon Volcano. This means that the volcano is undergoing a moderate level of unrest.
