A magnitude 4.9 earthquake near La Ligua, Petorca Province, Valparaiso, Chile, was reported only 13 minutes ago by the German Research Centre for Geosciences (GFZ), considered one of the key international agencies that monitor seismic activity worldwide. The earthquake occurred at a shallow depth of 10 km beneath the epicenter early morning on Wednesday, September 15th, 2021, at 3:47 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 European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.9 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 98 km from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Valparaiso (pop. 282,400) located 114 km from the epicenter, Viña del Mar (pop. 294,600) 117 km away, Hacienda La Calera (pop. 49,100) 117 km away, and Quillota (pop. 67,800) 122 km away.
