Some Berkeley residents felt a shake Wednesday morning when an earthquake hit the town of Isleton in the Sacramento Delta.

Others said they felt nothing at all.

The [magnitude 4.2](https://earthquake.usgs.gov/earthquakes/eventpage/nc73948665/executive?ref=berkeleyscanner.com)[ quake](https://earthquake.usgs.gov/earthquakes/eventpage/nc73948665/executive?ref=berkeleyscanner.com) occurred at 9:29 a.m. with a depth of about 6.7 miles, according to the U.S. Geological Service. (It was initially estimated as a magnitude 4.1.)

"Wife and I got alert 2 seconds before quake. Impressive!" one Berkeley resident wrote on the X platform, formerly known as Twitter.

"A good shake here in North Berkeley," wrote another.

Many people said they got an alert via the [MyShake app](https://myshake.berkeley.edu/?ref=berkeleyscanner.com) but did not feel the earthquake.

A Scanner post on X about the quake has garnered dozens of replies — with some saying they were frustrated because they got the alert but felt nothing.
