A shallow magnitude 6.2 earthquake was reported in the evening near Gigmoto, Catanduanes, Bicol, Philippines.
According to the United States Geological Survey, the quake hit on Tuesday, April 4th, 2023, at 8:54 pm local time at a shallow depth of 15 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the China Earthquake Networks Center (CEIC), which listed it as a magnitude 6.2 earthquake as well. Other agencies reporting the same quake include Geoscience Australia (GeoAu) at magnitude 6.2, the European-Mediterranean Seismological Centre (EMSC) at magnitude 6.2, the German Research Centre for Geosciences (GFZ) at magnitude 6.3, the German Research Centre for Geosciences (GFZ) at magnitude 6.3, the German Research Centre for Geosciences (GFZ) at magnitude 6.3, Italy’s National Institute of Geophysics and Volcanology (INGV) at magnitude 6.2, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) at magnitude 6.6, France’s Réseau National de Surveillance Sismique (RéNaSS) at magnitude 6.0, and the citizen-seismograph network of RaspberryShake at magnitude 6.2.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Gigmoto (pop. 3,300) located 124 km from the epicenter, Virac (pop. 15,100) 142 km away, and Laoang (pop. 16,700) 143 km away, the quake should have been felt as light shaking.
