SoCal earthquake in Wichita is so strong that it’s not even a quake, seismologist says

An earthquake in southwestern California was so strong and sudden that it was not a quake.
The magnitude-5.0 quake, centered just south of Sacramento, came as the nation awaited news on whether California would declare a state of emergency in the aftermath of the magnitude-6.0 earthquake that killed at least 20 people and injured hundreds of others in California.
The California Division of Earthquake Safety said the quake lasted roughly 6 seconds and was centered near the town of Lodi, about 80 miles (145 kilometers) south of San Francisco.
California Gov.
Gavin Newsom, a Democrat, said on Twitter that he was “shocked and devastated by the tragic death and destruction” in his state and urged residents to stay inside.
The U.S. Geological Survey said the epicenter was about 15 miles (25 kilometers) north of Lodie, about 25 miles (40 kilometers) west of the California-Oregon border.
No tsunami warnings were issued and the National Weather Service said it was unclear how strong the earthquake was.
The state is a major earthquake epicenter.
