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.

New Mapping Techniques Reveal Potential Seismic Sources Beneath Seattle

By Richard J. Blakely, Geophysicist and Ralph A. Haugerud, Geologist

 

  • Geophysical methods reveal "the landscape beneath the landscape"
  • Why does the Seattle Fault exist, and why is it so hard to locate and map?
  • LIDAR imagery can

The last dome-building eruption of Mount St. Helens during the 1980s occurred in October 1986. A new lobe was extruded, increasing the dome's height to 925 feet (282 meters), making it taller than a 77-story building. In volume, the dome was nearly 40 times the size of Seattle's Kingdome stadium. The view is from Harry's Ridge, five miles (8 kilometers) north of the
