Uncovering 14,000 Years of Seismic Activity in Northern Cascadia

New USGS research documents a 14,000-year history of seismic activity preserved in the sediments of Ozette Lake, a ~100-meter (328-foot) deep coastal lake on Washington State’s Olympic Peninsula. The study provides crucial insights into the long-term seismic behavior of the northern Cascadia subduction zone, one of the most tectonically active regions in North America.
