A mud avalanche occurred at Mt. Tukuba, Ibaraki prefecture, on July 3, 1938. In flowing down the valley it swept away two wooden buildings and killed three men. The avalanche was caused by collapse of soil in the upper waters of the valley as the result of heavy rains. The velocity of the flow was estimated to be less than 10 meters per second.
