Earthquake In California 6.0
On Thursday afternoon, local time, inhabitants from the Bay Area to the Great Basin were shaken by a strong tremor. There were no significant injuries or damage reported right away.
According to the US Geological Survey, the rumbling was caused by a preliminary Magnitude 6.0 earthquake that struck near the California-Nevada border at 3:49 p.m., around 20 miles southeast of Markleeville, California. It was approximately 4.6 miles deep. More than 30 aftershocks followed in the next two hours, as well as a “phantom quake,” according to one expert.
People who checked the USGS website immediately may have noticed a preliminary report of an M4.8 earthquake in Stockton, California, which occurred just after the M6.0 quake, only for the latter to vanish moments later.
“The Stockton ‘earthquake’ was most likely caused by a mistaken connection of some of the Nevada quake’s waves with a secondary source,” said Jascha Polet, a geophysics professor.
She alluded to the event as a probable “phantom quake,” or non-existent quake, in an earlier post.
“Automatic systems that locate quakes sometimes get confused,” a seismologist noted, “particularly if there are a few stations extremely close together.” “When those errors are fixed, the online pages are updated.” There is now no earthquake near Stockton, only to the south of Lake Tahoe, as you can see.
While the M4.8 was a miscalculation, the M6 and its aftershocks were quite real, and people from the Bay Area to the Great Basin felt them.
Users on social media from the Bay Area to Reno, Nevada, reported feeling the tremors, which included a few National Weather Service facilities.
“It’s only around a minute long. The blinds are moving. Moving in a light building motion/shaking motion, “Sacramento’s office sent out a tweet. The quake caused “quite severe shaking” in the Reno headquarters.
The Associated Press said that rockslides closed roughly 40 miles of U.S. 395, a main highway through the northern Sierra Nevada. According to the California Highway Patrol, a couple cars were hit, but no one was hurt. Although parts of the interstate were eventually reopened, personnel remained on the scene in case of any aftershocks.
Meteorologist noted that the earthquake ruptured along the eastern side of the Sierra Nevada, which is known to have several active faults. “Along a north-south axis, the fault mechanism suggests “normal” faulting.” This is compatible with documented crustal spreading beneath the Great Basin’s western border.”
