The Slope Base study site (Primary Node PN1A) is located near the foot of the continental slope about 60 miles (100 km) west of Newport, Oregon. This site is just west of the Cascadia Subduction Zone, where mega-earthquakes have occurred, producing tsunamis that impacted both NW coastal communities, as well as those along the east coast of Japan. The last magnitude 9 earthquake occurred in 1700. Just to the east, is the steep, continental slope that may result in strong topographic forcing effects on ocean currents.
