Well, it's California, so perhaps there's hope for civilization after all.

Caltech researchers used advanced imaging techniques to investigate increased seismic activity in California’s Long Valley Caldera, a dormant supervolcano.
Since the 1980s, researchers have observed significant periods of unrest in a region of California’s Eastern Sierra Nevada mountains characterized by swarms of earthquakes as well as the ground inflating and rising by almost half an inch per year during these periods. The activity is concerning because the area, called the Long Valley Caldera, sits atop a massive dormant supervolcano. Seven hundred and sixty thousand years ago, the Long Valley Caldera was formed in a violent eruption that sent 650 cubic kilometers of ash into the air—a volume that could cover the entire Los Angeles area in a layer of sediment 1 kilometer thick.

Scientists have measured the most well-travelled fast radio burst to date. The bright, briefly detectable flash of energy has barrelled through the Universe for around eight billion years — almost half the age of the Universe — before hitting telescopes on Earth. It is also more than three times more powerful than expected, challenging current models.
The age of the fast radio burst was the biggest surprise to the researchers, who published their findings today in Science1. “We didn’t know whether fast radio bursts even existed that far back in time,” says study co-author Stuart Ryder, an astronomer at Macquarie University in Sydney, Australia.
