Moderate yet deep magnitude 5.3 earthquake 13 km northeast of Calama, Chile

5.3 quake 1 Nov 11:37 pm (GMT -3)

An intermediate magnitude 5.3 earthquake was reported late at night near Calama, Provincia de El Loa, Antofagasta, Chile.
According to the United States Geological Survey, the quake hit on Tuesday, November 1st, 2022, at 11:37 pm local time at an intermediate depth of 109 km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. 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 Incorporated Research Institutions for Seismology (IRIS), which listed it as a magnitude 5.3 earthquake as well. Other agencies reporting the same quake include the European-Mediterranean Seismological Centre (EMSC) at magnitude 5.3, the citizen-seismograph network of RaspberryShake at magnitude 5.3, and the German Research Centre for Geosciences (GFZ) at magnitude 5.4.
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 Calama (pop. 143,100) located 13 km from the epicenter, Maria Elena (pop. 4,900) 79 km away, and San Pedro de Atacama (pop. 2,000) 95 km away.
