A magnitude 4.1 earthquake shook California’s Imperial County near the Salton Sea Monday morning.
The quake struck 18 miles south of Salton City and 4 miles southeast of Ocotillo Wells at 5:17 a.m., according the U.S. Geological Survey.
Residents as far away as Chula Vista, Mission Viejo, Highland and Indio reported feeling the quake, the USGS reported.

Monday’s quake comes amid a swarm of smaller quakes over the weekend.
Seismologist Dr. Lucy Jones posted a message about the earthquakes on X, formerly Twitter Saturday.
“The current quakes in the Imperial Valley are being called a swarm. These have been common in the Imperial Valley. As of 6:00pm on 5/18, we have 16 M≥3 events, near the Imperial Fault,” Jones stated.
There were no immediate reports of damage or injuries from Monday’s quake.
