A series of earthquakes measuring up to 5.4 rattled southern California, Arizona and the Mexican border region Sunday, seismologists said, although no damage or injuries were immediately reported.

The small- and medium-level quakes were felt from San Diego and Orange County in California east into Arizona, and swamped the temblor-measuring resources of the US Geological Survey (USGS).

The quakes began around 12:16 pm (2016 GMT) with a magnitude 4 temblor 16 miles (26 km) north of El Centro, California, and lasted more than two hours. The biggest shakes included a magnitude 5.4 at 13:57, with the same epicenter.
