4.2 quake 14 km W of La Ligua, Chile, 16 Nov 11.22 am (GMT -3)
A magnitude 4.2 earthquake was reported only 19 minutes ago by the European-Mediterranean Seismological Centre (EMSC), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at an intermediate depth of 71 km beneath the epicenter in the morning on Monday 16 November 2020 at 11.22 am local time. 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 National Seismological Center of the University of Chile, which listed it as a magnitude 4.2 earthquake 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. Weak shaking might have been felt in La Ligua (pop. 24,900) located 14 km from the epicenter.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Hacienda La Calera (pop. 49,100) located 38 km from the epicenter, Quillota (pop. 67,800) 48 km away, Llaillay (pop. 16,600) 57 km away, Limache (pop. 35,900) 62 km away, Viña del Mar (pop. 294,600) 64 km away, Quilpué (pop. 130,300) 65 km away, and Valparaíso (pop. 282,400) 67 km away.

If you did NOT feel the quake although you were in the area, please report it! Your contribution is valuable to earthquake science, seismic hazard analysis and mitigation efforts. You can use your device location or the map to indicate where you were during the earthquake. Thank you!

Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.
