With this improved knowledge we can better prepare for future strong temblors. But at the 11-degree bend which, interestingly, occurs near the peak named Loma Prieta in the Santa Cruz Mountains the San Andreas fault blocks no longer slide relatively easily past each other, causing rock to push up against each other and form the Sierra Azul, Hilley said.

Downtown San Francisco, the said report showed, is vulnerable; some of the oldest buildings survived by shaking back in 1906, although that does not mean they'd be safe in the coming earthquakes by any means. The question: Are we ready? And we can harness those into the network ultimately to create a more powerful warning," said Stein. The new likelihoods are due to the inclusion of possible multi-fault ruptures, where earthquakes are no longer confined to separate, individual faults, but can occasionally rupture multiple faults simultaneously, said lead author and USGS scientist Ned Field.
