More than three dozen aftershocks, ranging up to a magnitude 4.9, have been registered following a 5.7 earthquake about 150 miles northeast of Sacramento, officials said.
The first quake struck at about 8:47pm Thursday; its epicenter was about 27 miles southwest of the town of Susanville and seven miles west northwest of Greenville near Lake Almanor, according to the U.S. Geological Survey.
People on Twitter told the Times they felt the quake in Sacramento and Lodi, as well as in Reno and on the northwest shore of Lake Tahoe.
Officials in Susanville and Sacramento said the quake set off a number of home and car alarms and rattled windows, but there were no immediate reports of damage.
Within minutes of the first quake, more than 7,000 people reported feeling it on the USGS website.
A Chico resident told the Times he felt a slow roll that lasted about 30 seconds.
Dozens of smaller earthquakes followed in the Greenville area, including a magnitude 3.5 temblor at 8:55pm, a magnitude 4.9 at 1:02am Friday, and a magnitude 2.5 at 5:36am, according to the USGS.
“House shook pretty hard,” one man near Truckee told the Times.
In 2008 the Golden Guardian Exercise for Northern California was held here in Lake Tahoe with the scenario of a seiche wave occurring due to an earthquake. People snickered a bit as they do not understand the active faulting that we have right here. The seismic activity is what created this beautiful landscape and it’s interesting to learn about. Google “seiche wave lake Tahoe” and see the many scientific articles on the subject. Yearly we have scientists working our lake area and yearly they see the dramatic changes.
