Philippines: no danger of volcano eruption on Negros Oriental

Alexander Richter 10 Nis 2009

Canlaon Volcano in Canlaon City, Negros Oriental is not showing any sign of unrest, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS) in Negros." and there is no sign that tremors felt were the result of geothermal drilling in the area, so reported in the local media.

“Canlaon Volcano in Canlaon City, Negros Oriental is not showing any sign of unrest, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS) in Negros.”, so reported in the local media.

From March 31 to present, no earthquake linked to the volcano has been recorded, and there is no imminent danger of an eruption, the PHIVOLCS said.  Tanatan of PHIVOLCS, whose office has recently been transferred from Canlaon City to La Carlota City in Negros Occidental, at the same time debunked initial reports that the tremors felt last March 30 there were most likely caused by geothermal drilling of the Energy Development Corporation-Northern Negros Geothermal Production Field (EDC-NNGPF).

He declined to comment on the possibility of geothermal drilling as having caused the tremors, saying they do not have the evidence to prove such. Contrary to earlier published reports, Tanatan said PHIVOLCS could not be conclusive as to the cause of at least 20 tremors recorded by their earthquake sensor last week, as they were transferring their instruments to their new office in La Carlota.

At the time of the tremors, the PHIVOLCS was setting up their instruments in Negros Occidental, he added.
In fact, the PHIVOLCS could not also conclude that the tremors recorded last week were volcanic in origin, Tanatan said. According to Tanatan, if Canlaon Volcano would show some indicators of unrest, it is normal for PHIVOLCS to record even more than 100 tremors in one day due to volcanic activity.

The PHIVOLCS issued their statement following public speculation that geothermal drilling at the buffer zone of the Mt. Kanlaon National Park in the Negros Occidental side had caused the tremors.

(The government) would also look into the link between drilling activity at the buffer zone of the Mt. Kanlaon National Park and the volcano.

In the event of a repeat of the March 31 tremors, the PHIVOLCS-Negros can now make a plot with the use of four sensors and determine their cause and origin. The last recorded eruption of Canlaon Volcano was in October 2006, he said. Since then, no volcanic activity has been reported there, he added.”
