| "Some landslide disasters are triggered by the seismic force in the Fukuoka Seihou-Oki earthquake on March 20, 2005, although they didn't have anteccedent precipitation. The earthquake whose epicenter was located in the offshore of the city of Fukuoka had the magnitude of Mjma 7.0, and Mw 6.4-6.6, maximum acceleration of 489 gal in downtown Fukuoka. Almost failures occurred in this seismic event are shallow slides on the Granite steep slopes and collapses of embankment under the houses. There can be found some prominent cracks on slopes due to the displacement of slopes. These phenomena give us the data that provide conspicuous important information to understand the mechanism of slope instability as well as the susceptibility of failures in the earthquake. Hence, the overview of the landslides is given in this paper." |
