VOLCANO WATCH. The Philippine Institute of Volcanology and Seismology did not detect earthquakes in Mt. Kanlaon, an active volcano in Negros Island, for two days on March 9 and 10. However, the volcano remains under Alert Level 1, which means it is in abnormal condition and under a period of unrest, Mari-Andylene Quintia, a science research specialist at the Kanlaon Volcano Observatory, said on Wednesday (March 10, 2021).

BACOLOD CITY – For two consecutive days since Tuesday, there were no tremors recorded in Mt. Kanlaon, an active volcano in Negros Island, based on the series of updates issued by the Philippine Institute of Volcanology and Seismology (Phivolcs).
“Kanlaon Volcano’s monitoring network did not detect any volcanic earthquake during the 24-hour observation period,” the bulletins on March 9 and 10 stated.
On March 8, only one earthquake was recorded.
Mari-Andylene Quintia, a science research specialist at the Kanlaon Volcano Observatory based in La Carlota City, Negros Occidental, told the Philippine News Agency (PNA) on Wednesday that although they did not detect any earthquake, other parameters are still above normal, and the volcano remains at Alert Level 1.
“These include the sulfur dioxide emission, which is 583 tons per day, and slight inflation of volcano edifice based on our global positioning system and tilt data,” she added.
She said the public is still reminded to heed the warnings since Mt. Kanlaon is “at an abnormal condition and has entered a period of unrest”.
Latest bulletin of the Department of Science and Technology (DOST)-Phivolcs reiterated to the local government units and the public that entry into the four-kilometer radius permanent danger zone is strictly prohibited due to the further possibilities of sudden and hazardous steam-driven or phreatic eruptions.
DOST-Phivolcs is closely monitoring Kanlaon Volcano’s activity and any new development will be relayed to all concerned, it added.
On June 22, 2020, a series of tectonic earthquakes jolted some parts of Negros Occidental as Mt. Kanlaon’s seismic monitoring network recorded 136 tectonic earthquakes on the western flanks.
Evacuations were reported after two magnitude 4.7 earthquakes rocked areas surrounding the volcano and a series of aftershocks were also recorded.
The following day, some 104 earthquakes were detected. (PNA)
