The 2004 Niigataken Chuetsu Earthquake led to enormous damages on earth structures that we had have not experienced recently. The magnitude of the earthquake was 6.8 and the seismic intensity registered a higher 6 to 7 on the 7-point Japanese intensity scale, which corresponded to the level 2 seismic motion. The magnitude of this earthquake is not so huge and earthquakes of the same level will take place often in Japan. The damage on earth structures was so heavy that it affects the protection measures for earthquake disaster in Japan, especially on slope disaster. The JGS has been active not only to send the disaster investigation team and to have the report symposium, but also to organize the disaster investigation committee to make clear the damages and causes of enormous disaster. The JGS announced the propositions on geotechnical damages of the 2004 Niigataken Chuetsu Earthquake to contribute the society. This reports the content of propositions with the explanation of typical geotechnical damages in the earthquake.
