It is generally said that climate change is influencing the activity range and intensity of rain. Accordingly, engineers in charge of disaster prevention must plan measures in consideration of future weather conditions. This paper is based on one of the scenarios presented in the 5th AR of the IPCC and compares current data for hourly rainfall with predicted figures. The comparison between current and predicted weather conditions confirms the need to develop disaster prevention technologies as a countermeasure to future extreme weather conditions. R.T.R.I. is therefore developing a dynamic hazard mapping system. This system maps floods, large-scale slope collapse and tornados, and displays the risk of their occurrence over time on a monitor. The map also indicates the best places for trains to stop based on hazard simulation, and routes to shelter for passengers.
