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.

Landslides Can Cause More Landslides

The deadliest individual landslides in the U.S. recently were in places where there had previously been a landslide. Why do landslides happen in the same place instead of on nearby slopes that appear to be just as likely, if not more likely, to slide?
