WebSubduction Zones are Potential Tsunami Locations. Most tsunamis are caused by earthquakes generated in a subduction zone, an area where an oceanic plate is being forced down into the mantle by plate tectonic forces. The friction between the subducting plate and the overriding plate is enormous. This friction prevents a slow and steady rate of ... WebThis map shows areas of seismic risk from high (red) to low (grayish-green). The map is from a 2007 report (click here to download) on seismic design categories in Washington.
