Stronger quake rattles Southern California

A 7.1 magnitude earthquake has rattled a desert area of Southern California, US meteorologists say, in the biggest tremor to strike in two decades.
It struck at the shallow depth of 0.9km and its epicentre was near Ridgecrest, about 150 miles (240km) north-east of Los Angeles.
A 6.4 magnitude quake struck the same region on Thursday.
There were reports of power outages after the new quake. Thursday's event wrecked some homes in the region.
