3.4 quake: 3 Km SSE of Indios, Puerto Rico, 23 Oct 2020 08:15
Just 38 minutes ago in the early morning on 23 October at 4.15 am local time, a 3.4-magnitude earthquake struck near the town of Indios, Puerto Rico, with a recorded depth of 10 km below the surface, considered shallow in seismological terms.
The event was filed by the United States Geological Survey (USGS), the first seismological agency to report it.
Our monitoring service at VolcanoDiscovery identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.4 as well.
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.
Towns or cities near the epicenter where the quake might have been felt, based on preliminary calculations, include Indios (pop. 1,700) at a distance of 3 km with weak shaking, Guayanilla (pop. 5,200) at a distance of 6 km with weak shaking, Bayamón (pop. 203,500) at a distance of 84 km, and San Juan (pop. 418,100) at a distance of 93 km. In the latter places, the quake was probably not felt.
