![]() Nonetheless, the wider region is not densely populated and hence, the impact of the earthquakes was minor. The epicenters of the quakes were located near Calipatria, a city in Imperial County, California. More than 600 seismic shocks with the greater being of M 5.3 were recorded near the border with Mexico. Click on the video below to watch the impressive footage. Some of the rockslides were caught on camera. The Utah Geological Survey suggests that rockfalls are one of the most common types of ground failures caused by earthquakes greater than M 4.0 in the region. A witness mentioned that “boulders the size of cars” fell onto the highway in one location. The earthquake occurred about 20 miles southwest of Smith Valley, NV. A magnitude 6.0 (M6.0) earthquake struck Little Antelope Valley, California near the Nevada border on Jat 3:49pm local time (July 8 at 22:49 UTC). Some people made attempts to remove them but many were massive and could not be readily displaced. By Communications and Publishing July 8, 2021. Photographs retrieved from the site show large boulders scattered in many sections of the highway. In particular, about 64 kilometers of the route near the community of Willow Springs in Mono county were impacted by the ground failures with some vehicles being hit but with no injuries reported. So they transmit the earthquake energy really well,” Keith Knudsen, deputy director of the USGS’ Earthquake Science Center, stated. Despite reportedly being the largest seismic shock to strike the region since 1994, no significant infrastructure damage or injuries were reported.Ī series of rockslides triggered by the seismic shock resulted in the closure of US 395, a major route in the western United States that travels from the US-Canadian border in the north to the Mojave Desert in the south. ".the mountains ring like a bell when an earthquake happens there. This is why the temblor was felt in large distances. The earthquake was felt as far as Las Vegas with many communities in California and Nevada being affected. The geologic formations in the Sierra Nevada comprise hard rocks that result in little attenuation of the generated seismic waves. Each year seismic networks record more than 30,000 earthquakes with magnitudes (M) as small as 1.0 in California and Nevada. The epicentral depth of the temblor was 7.5 kilometers and it was followed by many shocks with the largest being M 4.6. The Sierra Nevada microplate is part of the Pacific-North America plate boundary system and moves at around 1,2 cm annually relative to the North American Plate. It hit on the eastern section of Sierra Nevada which comprises a physical boundary along the border of California and Nevada. According to the United States Geological Survey (USGS), the current seismic shock was a result of tectonic movement along a moderately dipping, normal fault on the North American Plate. local time in Antelope Valley about 400 kilometers east of San Francisco, California. Earthquakes in the area of interest usually occur along normal or strike-slip faults. The earthquake occurred at around 3:50 p.m. ![]() The seismic shock triggered rockslides along a major highway but, fortunately, no injuries were reported. The top three magnitudes greater than or equal to 3 are in red.A M 6.0 earthquake struck near the California and Nevada border on July 8, 2020. Magnitude 3 and greater earthquakes are printed in bold type. Click on an event "DATE" to get additional text information. Click on the word "map" or "MAP" to see a map displaying the earthquake.
