Abstract

A great earthquake (Mw 8.8) occurred offshore at central Chile on 27, Feb., 2010 in Japan time. Tsunami by this earthquake arrived at the Pacific coasts of Japan 22 hours after the occurrence. We surveyed the Tsunami Trace Height (TTH) and arrival times along the coast in the Kanto and Tokai districts. As a result, the TTHs were lower than 1.8 m and the arrival times were basically from 16:00 to 18:00. Along the surveyed coasts, the TTHs from the 1960 Chilean tsunami were 1 to 3 m, generally higher than the 2010 TTHs. However, at a few locations, the 2010 TTHs were locally similar or slightly higher than the 1960 TTHs.
