Fascinating explainer by the Chronicle’s David Perlman as to why Columbia University scientists now say Death Valley’s Ubehebe volcano, long thought to be extinct, could, in fact, go off again any time. New evidence suggests the eruption that created the half-mile-wide crater probably happened as recently as 800 years ago, not 6,000 years ago as previously thought. And that there’s enough water in the aquifer under it to cause Ubehebe to explode again in the near future.Noted: The crater is near the north end of Death Valley National Park, not to be confused with 5,678-foot Ubehebe Peak, 24 miles to the southwest.
