Abstract: The heavy rainfall which took place over the Goto Islands in Nagasaki Prefecture on 12-13 September 1989 is the object of this study. A landslide killed 4 persons at Kami-Goto Machi where had the strongest 1-hour precipitaion. The authors made an investigation into the actual amounts of rainfall in this district in order to provide a data set for disaster protection. The results can be summarized as follows: (1) The extremes in this rain storm, that is 23 mm in 10 minute and 108 mm in an hour, were both observed at Aokata in Kami-Goto Machi in midnight when the storm warning could not be propagated so promptly. (2) Although the intensitu of rainfall in a short time range was strongest in the northern parts of these islands, the total amount of precipitaion was larger in the south-western region especially at Miiraku Machi, where reached as much as 522.5 mm in 24 hours. (3) The Goto Islands is located in the western outskirts of the main land where the storm ordinarily comes in the earliest time, so that more careful watches by radar systems are strongly desired.
