Scientists identify more than 2k quakes at the Long Valley Caldera
- k310 3y agoQuote: California's supervolcano that has the power to bury Los Angeles in more than 3,000 feet of ash is showing signs of activity … The study author Zhongwen Zhan said: 'We don't think the region is gearing up for another supervolcanic eruption, but the cooling process may release enough gas and liquid to cause earthquakes and small eruptions. For example, in May 1980, there were four magnitude 6 earthquakes in the region OK - A bit hyperbolic because Long Valley is near Mammoth Lakes, more likely to dust up Mono Lake than Yosemite across the Sierras, due to prevailing winds. L.A. would have no piece of this action, and in the next few years, hundreds or thousands of years probably more earthquakes and possible volcanic eruptions.

The using-fiber-optic-cable-as-seismometer part is interesting. Wondering if this would work using existing fiber networks? Seismometers everywhere on the cheap?
