Small tremor of magnitude 3.4 just reported 6 miles northeast of Morgan Hill, California, United States
3.4 quake 18 Jun 1:14 pm (GMT -7)
3.4 quake 18 Jun 1:14 pm (GMT -7)
The United States Geological Survey reported a magnitude 3.4 quake in the United States near Morgan Hill, Santa Clara County, California, only 7 minutes ago. The earthquake hit around noon on Saturday, June 18th, 2022, at 1:14 pm local time at a very shallow depth of 2.9 miles. 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 citizen-seismograph network of RaspberryShake which listed the quake at magnitude 3.4 as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 3.4.
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 Morgan Hill (pop. 42,900) located 6 miles from the epicenter.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Gilroy (pop. 53,200) located 13 miles from the epicenter, San Jose (pop. 1,026,900) 20 miles away, Campbell (pop. 41,100) 21 miles away, Los Gatos (pop. 30,700) 22 miles away, Watsonville (pop. 53,600) 22 miles away, Santa Clara (pop. 126,200) 23 miles away, and Milpitas (pop. 77,600) 24 miles away.

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.
