The earthquake hit early morning on Monday, March 23rd, 2026, at 1:44 am local time at a shallow depth of 10. km. 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.Our monitoring service identified a second report from The National Seismological Center (Centro Sismológico Nacional, CSN) of the University of Chile which listed the quake at magnitude 4.3 as well. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 4.3.Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc. In Florida (pop. 8,900) located 7 km from the epicenter, the quake should have been felt as light shaking.Weak shaking might have been felt in Hualqui (pop. 24,300) located 25 km from the epicenter, Chiguayante (pop. 84,700) 32 km away, Penco (pop. 46,100) 33 km away, Concepcion (pop. 223,600) 35 km away, San Pedro de la Paz (pop. 121,600) 39 km away, Tome (pop. 46,700) 40 km away, Talcahuano (pop. 253,000) 44 km away, and Coronel (pop. 92,900) 45 km away.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
