Moderate magnitude 4.5 earthquake 61 km northeast of Arica, Chile
4.5 quake 30 Jan 5:22 am (GMT -3)
4.5 quake 30 Jan 5:22 am (GMT -3)
A intermediate magnitude 4.5 earthquake was reported early morning near Arica, Provincia de Arica, Arica y Parinacota, Chile.
According to the National Seismological Center of the University of Chile, the quake hit on Saturday 30 January 2021 at 5:22 am local time at an intermediate depth of 118.3 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 United States Geological Survey (USGS), which listed it as a magnitude 4.8 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.5.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Tacna (pop. 280,100) located 56 km from the epicenter, and Arica (pop. 186,000) 61 km away.
