On 18 July 2004, a localized heavy rainfall occurred in the Fukui area, which is located on the Japan-Sea side of the Japan Islands, in conjunction with the intensified Baiu-front. The Fukui heavy rainfall resulted in many disasters, e.g., landslide, debris flow, dyke-break and flood, especially in the Reihoku district of Fukui Prefecture. One of the most damage was caused by water from a broken dyke of Asuwa-river in Fukui City. This paper discuss about Fukui rain from a view point of remote-sensing. Remote-sensing data of Goes 9, Modis (500m resolution), Aster (15m resolution), Ikonos (1m resolution) and Aerial orthophotograph (33cm resolution) are used. The aspects of disasters are shown in many processed images. The false-color image of Aster is useful for the disaster detection.
