The Big One: Chances of major California earthquake TRIPLE | Daily Mail Online

Ross Stein, an author of the study who was previously a geophysicist at the US Geological Survey, told the Los Angeles Times: ‘The Ridgecrest earthquake brought the Garlock fault closer to rupture.

“If that fault ruptures — and it gets within about 25 miles of the San Andreas — then there’s a high likelihood, maybe a 50-50 shot, that it would immediately rupture on the San Andreas.’

The ‘Big One’ is a hypothetical earthquake of magnitude 8 or greater that researchers have warned will one-day happen along the San Andreas fault.

Such a tremor could produce devastation to human civilization within about 50-100 miles of the quake zone, especially in urban areas like Palm Springs, Los Angeles and San Francisco.
