Just before the earthquake, residents reported getting an alert on their phone from the USGS Shake Alert system.
"Earthquake detected! Drop, cover, hold on. Protect yourself," the alert read.
The alert came as Tropical Storm Hilary was centered less than 100 miles from San Diego, California, Fox Weather reported.
Torrential rains are expected from the storm, which could trigger life-threatening flooding through Monday.
