Earthquake in Nevada

 

A 6.5-magnitude earthquake struck at 4:03 a.m. today about 60 miles east of Mono Lake near Tonopah, Nevada, and the shaker was strong enough to jiggle the central Sierra Nevada mountain range and waken people all over California, including Sonora and the rest of the Mother Lode.

Instruments initially measured the temblor at 6.4M and that was upgraded to 6.5M within about an hour of the abrupt jolting jump in the earth’s crust, 175 miles east of Sonora. Mother Lode residents from Twain Harte to Angels Camp also felt the quake and tweeted or responded to tweets about how the shaking woke them up in predawn darkness.

The U.S. Geological Survey measured the epicenter of the quake 1.7 miles below the earth’s surface, about 35 miles west of the tiny high Eastside desert town of Tonopah, east of U.S. 95 and Mono Lake and U.S. 395.

The quake cracked sections of U.S. 95 that were closed in Nevada due to the damage, and with the upgrade to 6.5-magnitude it was the strongest temblor to strike in Nevada since a 7.1M quake measured in 1954, the Nevada Seismological Lab and The Reno Gazette-Journal reported.

Within about 20 minutes of the temblor, 55 people had responded to the online USGS Did You Feel It page designated for the quake, including responses from Fresno, San Jose and Sacramento. Twenty minutes later there were more than 8,400 responses, the vast majority in California communities on the west side of the Sierra Nevada range. Five hours after the initial shocks were felt in Sonora, there were more than 16,000 DYFI responses to the USGS for the 4:03 a.m. quake.
