A new observation system for rocky mudflow was designed by the Mudflow Research Group.The system consists of a detector on mudliow arrival and automatic switch circuit for VTR, 35mmcamera and firing of flare tube in order to record the state of moving mudflow. In addition to thissystem, rain gauges and water level recorder are necessary for the survey of hydrological characterin a small mountaineous basin. During last summer in 1970, the observation system and hydrolo-gical survey instruments had been set along Kamikamihori valley at eastern slope of Mt. Yake andtested in regard to the practical effectiveness. The front velocity (1-5 m/see) of mudflow wasmeasured correctly from the record obtained by the new system.
