PHIVOLCS monitoring Mt. Kanlaon water sources for possible contamination

BACOLOD CITY — The Philippine Institute of Volcanology and Seismology (PHIVOLCS) is monitoring open water sources on the slopes of Mt. Kanlaon in Negros Island Region as steaming activity from the summit continues.

Jay Jamello, PHIVOLCS science research specialist in Negros Occidental, said late Wednesday that despite the rains, the steaming activity in the crater is evident.

There is still steaming activity from the summit, and the crater is emitting a white steam smoke, although there is no ashfall, he added.

Jamello noted that the emitted white steam plumes, which rose up to 800 meters, drifted towards northwest and southwest.

He added that open water sources may be contaminated by the ashfall spewed by the volcano during its eruption last June 18, but so far they have not received reports that rivers and streams are affected.

During the eruption last Saturday, light ashfall was monitored on the western slopes of the volcano, affecting Barangays Ara-al, San Miguel and Yubo in La Carlota City, Barangay Sag-ang in La Castellana, and Barangay Ilijan in Bago City.

Last March 29, Mt. Kanlaon also recorded two minor eruptions and ejected incandescent materials.

Mount Kanlaon remained under Alert Level 1 status, which means it is at an abnormal condition and is in period of current unrest, which is probably driven by hydrothermal process that could generate more minor eruptions, Phivolcs said.

The active volcano has been on unsettling status since November 23 last year. PNA/
