Abstract

The 2004 Mid-Niigata Earthquake induced many landslides in the Uonuma Mountains. Larrge landslides of oll otehers occurred in the watershed of the Imokawa river that locates in the eastern side of that mountains where large landslide geomorphology is relatively not dense.On the other hand, a few landslides ccurred in the central area of the Uonuma mountains where large scale landslide geomorphology is highly dense distributed . Such distribution of the earthquake triggerd landslides means that large scale landslides tend to occurre along the "landslide front"where mountain releif is large and river incision is highly active than other areas. This tendency would reflect the active uplifting of the Uonuma Mountains and the 2004 Mid-Niigata Earthquake is also one event of uplifting.
