“Troubled Edens,” the latest film by KUED’s John Howe, explores the numerous challenges facing these beloved parks.

Today is the 50th anniversary of the U’s Seismograph Stations, which now include 237 seismic-recording stations located in Utah, Wyoming and Idaho to monitor earthquakes throughout the world and the region.

After spending decades tromping around Yellowstone and Grand Teton national parks to study their volcanic and seismic hazards, awards keep pouring in for Bob Smith, a research and emeritus professor of geology and geophysics.

U seismologists discovered a reservoir of hot, partly molten rock beneath the Yellowstone supervolcano, and it is four times larger than the shallower, long-known magma chamber.
