Significant 5.1 quake hits near Basco, Batanes, Cagayan Valley, Philippines

Just 22 minutes ago, a 5.1-magnitude earthquake struck near Basco, Batanes, Cagayan Valley, Philippines. The tremor was recorded in the afternoon on Tuesday, January 31st, 2023, at 4:49 pm local time, at a shallow depth of 10 km below the surface.
The event was filed by the German Research Centre for Geosciences (GFZ), the first seismological agency to report it.
Our monitoring service identified a second report from the citizen-seismograph network of RaspberryShake which listed the quake at magnitude 4.5. Other agencies reporting the same quake include the Philippine Institute of Volcanology and Seismology (PHIVOLCS) at magnitude 4.0, and the European-Mediterranean Seismological Centre (EMSC) at magnitude 5.1.
Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Basco (pop. 7,300) located 82 km from the epicenter.
