This time, some say it’s a possibility. “The magnitude of this event is bigger than any U.S. or Russian test since the early ’70s,” said Brian Stump, a seismologist at Southern Methodist University, which operates two seismic detectors for the Comprehensive Test Ban Treaty Organization.

Shock waves from the explosion clearly registered on the SMU-operated detectors near Big Bend National Park in Texas and in Mina, Nev.  Here’s what scientists know about the event — and how they know it. READ MORE
