Episode 388: University of Arizona tree ring researcher Bryan Black

A devastating earthquake that struck what’s now the northwestern corner of the United States 1,100 years ago is still part of native American legend in the region. University of Arizona tree ring researcher Bryan Black is leading a team discovering more about the event and reveals how linked fault lines beneath the Earth’s crust might pose a further threat to the region in the present day.

Bryan Black spoke with Tim Swindle, professor emeritus in Planetary Science at the University of Arizona.
