The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded five earthquakes across southern Negros yesterday, with all but one striking Negros Oriental.
All of yesterday’s tremors struck in the morning, with the first recorded west of Hinoba-an, Negros Occidental around 2:37 a.m. The 2.4-magnitude quake is the third to hit the area in recent weeks. A similar magnitude earthquake hit the town last week, while a 2.0-magnitude tremor occurred last month.
Starting around 5:08 a.m. until 6:28 a.m., three minor earthquakes were recorded in the waters off Basay, Negros Oriental. The first one was the strongest, recording a magnitude 3.1, with the other two slightly declining to 2.7 and 2.6. The town was struck by two successive earthquakes towards the end of last month, with 2.2 and 3.1-magnitude tremors occurring within four minutes of each other.
By 8:21 a.m., the fifth earthquake struck west of Guihulngan City, Negros Oriental, measuring 2.0 in magnitude.
Phivolcs reported no damages as a result of any of the tremors.
Based on magnitude, earthquakes ranging between 1.0 and 3.0 are often classified as a Level 1 on the Mercalli intensity scale, where very few even feel the tremor. However, a 3.1 is typically considered a Level II, where some people are able to feel movement, particularly on the upper floors of buildings./WDJ
