UPTwomvOcJ- Heidi Hatch KUTV July 9, 2021Īt one point, rockslides closed about 40 miles of the interstate, a major route through the northern Sierra Nevada, authorities said. SCARY: Check out these boulders knocked loose during the earthquake on the Nevada – California border. But the shaking continued, and “boulders the size of cars” fell onto nearby US 395, she said.Ĭars were struck by rocks, but nobody was injured, the California Highway Patrol reported. “We ran out of the building,” Estrada said. The shaking lasted 30 seconds or more, she said. Boulders block US Route 395 near the border of California and Nevada following an earthquake on July 8, 2021. Syrup bottles broke, dishes fell to the floor and the roof of the shop caved in a bit. “The ground was shaking pretty bad, and then everything started falling,” said Carolina Estrada, manager at the Walker Coffee Company. It was followed by dozens of aftershocks, with at least a half-dozen of magnitude 4.0 or greater, the USGS said. Its epicenter was four miles west-southwest of Walker, a California town of fewer than 900 residents. in a region about 250 miles east of San Francisco and south of Lake Tahoe. There were no immediate reports of serious damage or injuries. SAN FRANCISCO - An earthquake with a preliminary magnitude of 6.0 rattled the California-Nevada border Thursday afternoon, with people reporting feeling the shaking hundreds of miles away, according to the US Geological Survey. Mexico rattled by another powerful earthquake, at least 2 dead Mexico earthquake creates ‘desert tsunami’ in national park 1,500 miles away Seismic and geodetic data will greatly aid in a final explanation.Dinosaur-killing asteroid caused ‘mega earthquake’ that lasted monthsĮarthquake looms as anglers land doomsday fish: ‘We are all going to die!’ One plausible tectonic explanation is that the fault slip occurred along a thick zone rather than on a single fault surface, that the fracture is a steep reverse fault or an overthrust dipping southeast, and that the faulting is extending or lengthening southwestward. #Recent california earthquakes seriesAmong peculiarities of the earthquake were: occurrence of the very strong shock on a fault showing little evidence of recent activity trend of fault at right angles to San Andreas and most other active faults in California relatively low intensity of the shock epicenter of main shock very near southwestern end of epicenter series asymmetry of isoseismals of apparent intensity lack of simple trace diversity in nature and directions of movement on surface ruptures and the small displacements on ruptures compared with the shortening in railroad tracks. Southern Pacific tracks crossing the zone were shortened 10-15 feet. Numerous ruptures, some several miles long, with diverse trends and directions of movement, cut the surface along the fault zone. Judged from some other earthquakes the displacement on the fault at depth was probably between 10 and 20 feet but no continuous simple trace developed on the surface. The northeast half is in plutonic rocks with virtually no sediments and is affected by large-scale landsliding from the 5,000-foot Bear Mountain scarp. The southwest half of the fault is beneath San Joaquin valley alluvium and gives little or no surface expression, but geophysical data indicate 10,000 feet or more vertical offset. The July 21, 1952, Arvin (Tehachapi) earthquake, the strongest shock in Southern California since 1857, presumably resulted from movement on the northeast-southwest-trending White Wolf fault near the south end of the San Joaquin valley.
