Earthquakes can strike at any moment.

On the final Season 1 episode of FieldSound, UW seismologists Harold Tobin and Audrey Dunham discuss the impending threat of “The Big One” – a large-scale earthquake that will strike along the Cascadia Subduction Zone.

Tobin and Dunham also share recent advances in earthquake and tsunami preparedness for communities inland and along the coast in the Pacific Northwest.
