There is a high possibility of occurence natural dams when deep seated catastrophic landslide occur. Then, in that case, it increases the likelihood of attacks against upstream area and downstream area. Therefore, it is important to rapidly detect sediment disaster.

In this study, to clarify relationship of sediment transport or attacking bank and ground vibration, we analyzed ground vibration data of occured deep seated catastrophic landslide.In this results, we understand that it bears a distinct relationship to ground vibration and sediment transport. Therefore, we determined that it may detect natural dams using seismometers.
