Over two dozen earthquakes have been reported to hit the California-Nevada frontier early Wednesday morning, with tremors being felt as far north as Sacramento as well as San Francisco and Las Vegas. The earthquakes struck near Lake Tahoe, and their rumblings were felt across areas of both states, KTVN reported. There were no immediate reports of problems. The US Geological Surveys says two magnitude 5.7 temblors were both centered in a remote area of Nevada near the California line, about 70 miles southeast of Lake Tahoe. At least seven quakes with magnitudes between 3 and 5.6 were reported shortly afterward, according to The Los Angeles Times. The moderate quakes, which struck at 12:18am local time and then four minutes later, were followed by a series of smaller aftershocks. The Mineral County Sheriff's Department in Hawthorne, Nevada, near the epicenter, says staffers felt both quakes, but they have not had any reports of injury or damage. The office says the quakes apparently did trigger burglar alarms at two businesses, and caused a rock slide that did not block a nearby highway. In addition to Lake Tahoe, the USGS says the quakes were felt in such areas as Carson City, Nevada, and Yosemite National Park and Mammoth Lakes in California, all roughly 60 miles from the epicenter. Social media users in Sacramento reported feeling the tremors. A reporter for KWTV News tweeted that there have been at least 28 reported earthquakes since the early morning hours in California and Nevada. A map put out by the Southern California Earthquake Data Center shows that in the last week that have been almost 700 light-to-moderate tremors in the area.
