Significant magnitude 5.3 earthquake 115 km west of Castro, Chile

5.3 quake 6 Jul 10:12 am (GMT -5)
5.3 quake 6 Jul 10:12 am (GMT -5)
A shallow magnitude 5.3 earthquake was reported in the morning near Castro, Chiloé, Los Lagos, Chile.
According to the European-Mediterranean Seismological Centre (EMSC), the quake hit on Wednesday, July 6th, 2022, at 10:12 am local time at a shallow depth of 10 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 citizen-seismograph network of RaspberryShake, which listed it as a magnitude 5.2 earthquake. A third agency, the German Research Centre for Geosciences (GFZ), reported the same quake at magnitude 5.5.
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 Castro (pop. 29,900) located 115 km from the epicenter, Chonchi (pop. 12,600) 118 km away, Ancud (pop. 28,000) 123 km away, and Dalcahue (pop. 13,100) 124 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
