The earthquake epicenter was located 7 miles northeast of Borrego Springs, about 25 miles southwest of Coachella, and struck at a depth of 7 miles. Deeper quakes are less noticeable. Quakes just below the earth’s surface — in the 0 to 10 miles range — can cause damage at lower magnitudes.

The San Diego County sheriff’s department told the Associated Press there were no initial reports of damage.

The quake’s magnitude was first reported Sunday as magnitude 4.1 but was reclassified by mid-morning.
