Washington

Washington's Puget Sound is a complex ecosystem directly adjacent to a robust metropolitan area that scientists from the USGS Western Fisheries Research Center study. Recent surveys have looked at juvenile surf smelt, a key link in the food web that are consumed by predators such as salmon, orca, and many marine birds.

3-D simulations of M9 earthquakes on the Cascadia Megathrust: Key parameters and uncertainty

Geologic and historical records indicate that the Cascadia subduction zone is capable of generating large, megathrust earthquakes up to magnitude 9. The last great Cascadia earthquake occurred in 1700, and thus there is no direct measure on the intensity of ground shaking or specific rupture parameters from seismic recordings. We use 3-D numerical...
