California braces for aftershocks

Ridgecrest (United States) - No fatalities or serious injuries have been reported from this second quake.

Emergency rescue crews fanned out on Saturday (July 6) to assess damage from the second powerful earthquake to hit Southern California in as many days - a 7.1 magnitude tremor that revived fears of the so-called Big One the region has feared for decades.
No fatalities or serious injuries have been reported from this second quake, the largest in Southern California in more than two decades. It hit on Friday night in a remote and sparsely populated area around 240km northeast of Los Angeles, where it was also felt. But the earth's mighty twitch shook buildings, damaged roads and rattled people still jittery from a 6.4-magnitude earthquake in the same region on Thursday.
The two major quakes, along with multiple aftershocks, have revived fears of the 'Big One' - a powerful tremor along the San Andreas Fault that could devastate major cities in Southern California. "This is an earthquake sequence. These earthquakes are related," said Caltech seismologist Lucy Jones.
There was a 10 per cent chance of Friday's quake being followed by another magnitude 7.0 or higher quake in the next week, she added.
According to the US Geological Survey, the chance of an earthquake of magnitude 3 or higher is more than 99 per cent.
