The National Research Institute for Earth Science and Disaster Prevention (NIED) operates the following facilities:

1. Large-Scale Rainfall SimulatorPDF(1.1MB)

Beginning in 1974, the large-scale rainfall simulator, the world's largest, has been used to find ways to prevent or lessen the extent of natural disasters that are caused by rainfall events. NIED has used the simulator to promote advances in basic and applied research on sediment-related problems such as landslides, erosion-oriented issues caused by heavy rains, and flood disasters involving basin development. NIED also conducts funded research experiments on the drainage inspection of sewer and piping access ports, the performance deterioration of optical fiber for communications and on radar.

2. Multi-Parameter Radar MP-XBlank / MP-Ka/W (in preparation)

Since 2000, NIED has been conducting a study for the prediction of landslide disasters caused by torrential rainfall. In 2003, the NIED X-band multi-parameter radar (MP-X) was installed in Ebina, Kanagawa prefecture, and continuous observation of rainfall began. The data obtained from such observations is used not only to predict landslide disasters, but also to reduce natural disasters resulting from rainfall. Through its observations, NIED aims to achieve the following:

3. Hiratsuka Experiment Station

TThis is the homepage of the NIED Hiratsuka Experiment Station. All kinds of sensor data sent from the Marine Observation Tower, which is set up 1km off Hiratsuka on Sagami Bay, are inspected. Publically accessible data can also be downloaded from the Hiratsuka Experiment Station website.
