Moreover, it is expected that the local torrential rain would increase continuously because of the climate change to the near-tropical climate that has been caused by the global warming. Under this circumstance, the monitoring of the slope failure disaster is required. There are several existing methods to predict of slope failure. The first traditional method is observation underground water. However, it is required preparing huge gauge in the deep ground. The second is observation landform displacement. This method requires huge size of equipments to deploy on the whole. Hence, it is difficult to cover of the wide area using expensive sensor units. Even worse, to collect sensing data via cables make it difficult to monitor the sliding land in real-time at the time of disaster. To solve above issuers, we have developed a slope failure disaster forecasting system using a wireless network. The pickets with multiple sensors, which are called iPicket, are driven to the ground. The iPicket has axis acceleration sensor on top. The acceleration sensor can use wireless sensor network. At the First stage of this research, we tried to monitor iPicket behaviors in real field.},
