The US Geological Survey says two earthquakes have rattled a desert area straddling the US-Mexico border. There were no immediate reports of injuries or damage on the US side.
The first quake struck on Friday morning in an area about 26 kilometres south of the Mexican border town of Mexicali. Its magnitude was measured at 4.8.
The second quake hit three minutes later, about eight kilometres farther south. It measured at 4.4.
It was the second time this week the region has been shaken. On Tuesday, a magnitude 5.0 quake hit an area about 34km southeast of Mexicali. No injuries were reported in that temblor. (AP)
