Kanlaon Volcano logs 11K tons of gas emission

State seismologists noted an increase in the sulfur dioxide emitted by Kanlaon Volcano after it released an average of 11,566 tons a day, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Wednesday. 

According to the advisory issued at 7 p.m., this is the highest emission from the volcano recorded since instrumental gas monitoring began. 

Phivolcs noted increased seismic activity at the volcano in Negros Island last September 9, just three months after it erupted in June.

Kanlaon remains at Alert Level 2 but state seismologists warned that the series of volcanic earthquakes may lead to another eruption. 

Phivolcs said sulfuric fumes were reported in the following localities:  Brgy. San Miguel, La Carlota City; Brgy. Masulog and Brgy. Pula, Canlaon City; Brgy. Codcod, San Carlos City; Brgy. Inolingan, Moises Padilla. 

“Prolonged exposure to volcanic SO2, especially of communities within direct reach of accumulation from plumes during low wind conditions, can cause irritation of the eyes, throat, and respiratory tract,” the Phivolcs warned. 

“People who may be particularly sensitive are those with health conditions such as asthma, lung disease and heart disease, the elderly, pregnant women and children.”   

Residents nearby are also advised to cover their mouth and nose with a damp clean cloth, or dusk mask. 

Entry into the volcano's four-kilometer permanent danger zone remained prohibited. Flying aircraft close to the volcano is also barred.—Vince Ferreras/LDF, GMA Integrated News
