摘要：A drastic change in the behavior of the 2011 Tohoku earthquake tsunami at specific sites or on a local scale was caused by changes in coastal setting, land uses for fisheries, large-scale river course changes, and coastal construction works such as super embankments, jetty ports, dredged ports and types of breakwater seawalls. Such phenomena could be identified along not only the coast of Tohoku close to the epicenter, but also that of Hokkaido, relatively far from there. This report presents some remarkable examples of the influence of man-made structures and land-use on the site-specific to local tsunami behaviors along the Pacific coast of Tohoku and Hokkaido from the geomorphological view, and must provide the information for the adequate mitigation to future tsunami disasters and evacuation from them.
