Content:
seismically induced seiches in inland lakes, seiches induced by tsunamis, and a combination of less severe seiches coincident with runoff floods should be provided. 5. Tsunami: The application should include the complete history of tsunami in the vicinity of the site. Both near and far-field tsunamigenic sources should be considered. Shallow seismic sources that are located on land, but are near the coast may generate an oceanic tsunami and should be considered. Far-field sources that may generate a tsunami that can travel long distances to affect the proposed site should be considered. Hillslope failures and slides that are generated on land and impact a water body (also called sub-aerial slides) may generate tsunami-like waves and should be considered. Submarine landslides are also known to generate tsunamis and should be considered. Seismic events can also generate tsunamis in inland water bodies, e.g., the tsunami-like wave generated in the Mississippi River due to the February, 1812, New Madrid earthquake. The possibility of such events affecting an inland site should be investigated. 2.4.2-7 Revision 4 - March 2007 6. Seismically Induced Dam Failures (or Breaches): The application should include the flooding hazard at the plant site resulting from seismically induced dam failure upstream of the site location. A complete listing of all dams and other relevant water control structures upstream of the site that may pose a flooding hazard to the site should be presented. The effects of dam failure induced flooding in plant design bases should be provided. The maximum water surface elevation should be provided from failure of one or multiple dams during the SSE coincident with a 25-year flood and 2-year wind waves, from failure of one or multiple dams during the OBE coincident with a SPF and 2-year wind waves, from failure of one or multiple dams during other earthquakes of lesser intensity coincident with runoff, surge, or seiche flooding, and from breaches of
