3.4 quake 8 Dec 10:38 pm (GMT -8)
A very shallow magnitude 3.4 earthquake was reported late at night near Ventura, Ventura County, California, USA.
According to the United States Geological Survey, the quake hit on Wednesday, December 8th, 2021, at 10:38 pm local time at a very shallow depth of 6 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 3.4 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 Carpinteria (pop. 13,700) located 5 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Ventura (pop. 96,800) located 10 miles from the epicenter, Santa Barbara (pop. 91,800) 15 miles away, Oxnard (pop. 207,300) 19 miles away, Port Hueneme (pop. 22,400) 20 miles away, Goleta (pop. 30,900) 22 miles away, Santa Paula (pop. 30,500) 23 miles away, Isla Vista (pop. 23,100) 23 miles away, and Camarillo (pop. 67,600) 26 miles away. In Valencia (pop. 148,500, 49 miles away), the quake was probably not felt.

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.
