The Lovejoy Buttes are great news if you've feared the San Andreas fault would eventually send Los Angeles into the ocean

A new study that has not yet been punctured as nonsense, to my knowledge:

when the Big One does hit, it may be less devastating than once thought, at least near Los Angeles. According to new work presented this week at a meeting of the American Geophysical Union, the ground there will shake up to 65% less violently than official hazard models suggest.

The good news for Angelenos stems from five rocks balanced precariously on top of other rocks in Lovejoy Buttes, a place in northern Los Angeles County that sits just 15 kilometers from the fault. By dating when the rocks first became fragile and analyzing their structures to assess the maximum shaking they could withstand, the researchers could test official predictions against thousands of years of earthquakes. Those predictions have been found wanting
