Map of people reporting feeling the quake near LA last evening
Thousands of people felt a moderate magnitude 4.3 quake that shook L.A. last evening shortly before 8 pm local time on Sep 17, 2021.
Its epicenter was in Carson, near Long Beach, and the quake was caused by strike-slip motion (side-by-side sliding) on a fault near the Newport-Inglewood fault zone, USGS reported.
There was no significant damage. Small aftershocks can be expected over the next several hours.

Moderate magnitude 4.3 earthquake 1 miles southeast of Carson, California, United States
4.3 quake 17 Sep 7:58 pm (GMT -7)
4.3 quake 17 Sep 7:58 pm (GMT -7)
An earthquake of magnitude 4.3 occurred early evening on Friday, September 17th, 2021, at 7:58 pm local time near Carson, Los Angeles County, California, USA, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a shallow depth of 9.1 miles. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 4.2 earthquake.
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 Carson (pop. 93,300) located 1 miles from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Torrance (pop. 148,500) located 4 miles from the epicenter, Gardena (pop. 60,400) 5 miles away, Compton (pop. 98,500) 6 miles away, Long Beach (pop. 474,100) 6 miles away, San Pedro (pop. 78,400) 6 miles away, Hawthorne (pop. 88,500) 8 miles away, South Gate (pop. 96,400) 10 miles away, and Los Angeles (pop. 3,971,900) 16 miles 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.

If you felt this quake (or if you were near the epicenter), please share your experience and submit a short "I felt it" report! Other users would love to hear about it!
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.
