Toppled rock blocks from the steep cliff along the Echizen Coast, Fukui Prefecture, hit apart of the shelter (rock-shed) below, and 15 persons in a micro-bus just passing there were killedby the breakage of the shelter on July 16th, 1989. The rock falls foregoing the toppling at leastfor one hour were reported by two eye-witnesses who had watched the full-process of the rock wallcollapse. Their statements give cleary the mode of the collapse starting with the tilting (toppl-ing) of a part of the joint block composing the partly over-hanged sea cliff. The joint block tiltedabout 30 degrees was then disintegrated, falling vertically on the earth surface. Distribution ofthe scattered blocks after the fall suggests the rotation of the blocks around an inclined axis atthe base of the cliff. The rotation is also confirmed by the fabric analysis of the distributed blocks.A part of the disintegrated blocks hit the rock-shed roof at its edge. Intensity of the impactforce given to the soil-covered roof is estimated to be 1100 ton-force, assuming the volume andsize of the individual block deduced from the survey after the fall.
