INLAND EMPIRE, CA — Back-to-back earthquakes rattled the Inland Empire Thursday, but there were no immediate reports of injuries or damage.

The first temblor measured a magnitude 2.5 and struck at 11:54 a.m. just southwest of Salton City, near the Salton Sea, according to the U.S. Geological Society. A second quake initially measuring a magnitude of 3.3 struck the same region less than a minute later, the USGS reported. Shortly after the report, the agency upgraded the second temblor to a magnitude 3.6.

About 130 miles north of the area, another magnitude 3.3 quake struck at 12:30 p.m. near San Bernardino County's Lytle Creek, according to the USGS reporting map. About an hour later, a smaller magnitude 2.9 temblor struck the same area, the agency reported.
