    Pacific Northwest Coastal Environments: Earthquakes and Sea Level Rise investigates the potential impacts of changes in global sea level by examining historical sea and land levels, projected future levels, and by determining how those changes may affect future tides and storm surges to inform their potential to cause harmful impacts. This region has a unique interaction of land, sea, and tectonics, and climate change can initiate issues ranging from an inundation of coastal areas due to both sea level rise and potential tsunami, to the retreat of coastal shorelines due to erosion caused by both tidal action and wave runup.

    • Presents sea cliff retreat mitigation techniques.
    • Discusses interaction between subduction zone earthquakes and vertical land movement.
    • Includes case studies of wave refraction and reflection.
