Negros Occidental was struck by two earthquakes yesterday morning with a 3.9-magnitude tremor striking Cauayan while, earlier that morning, a 2.1-magnitude quake was recorded near Sipalay City.
According to the Philippine Institute of Volcanology and Seismology (Phivolcs), no damages were recorded as a result of the seismic activity nor were there any anticipated aftershocks.
The agency noted, the Cauayan quake resulted in an Intensity II, where a few people feel the tremor, particularly those on the upper floors of buildings, in Bago City; while an Intensity I, where the tremor goes almost undetected, was recorded in La Carlota City.
With regard to the Sipalay City tremor, quakes ranging between 1.0 and 3.0 in magnitude are often classified as an Intensity I.
Phivolcs raised the alert level for Mt. Kanlaon to “Alert Level 1” earlier this month after recording new activity in the area. Based on a bulletin issued on March 11, the seismic monitoring network at the volcano recorded at least 80 volcanic earthquakes since March 9./WDJ
