Moderate magnitude 4.9 earthquake 98 km northwest of La Ligua, Chile

4.9 quake 15 Sep 3:47 am (GMT -5)
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.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you're in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.

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.
