The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded a minor earthquake last Sunday, with an epicenter located just west of La Libertad, Negros Oriental. The 2.2-magnitude tremor marks the tenth minor quake to shake the island since mid-August, when a 2.0-magnitude earthquake struck the vicinity of Hinoba-an, Negros Occidental.
The earthquake registered just after 4:00 p.m.
Considered a Level 1 on the Mercalli intensity scale, where very few feel the tremor, a Phivolcs report found no damage recorded and no aftershocks expected.
The day before the La Libertad quake, around 8:49 p.m., a 2.2-magnitude earthquake was also recorded in the waters just west of Siaton, also in Negros Oriental.
In a report by the United States Geological Survey, the agency discussed the concept of foreshocks, which are smaller earthquakes that occur in the same area and may serve as predecessors for a larger quake; however, they note, scientists are still unable to successfully predict earthquakes./WDJ
