Disastrous snow avalanches which occurred in the Hokkaido Island, Aomori-, Iwate-, Akita-, Yamagata-, Miyagi- and Fukusima-kens were surveyed from 1926 to 1981 through local newspaper articles and archived. Prefectures where these avalanches were recorded frequently were Hokkaido Isl., Yamagata and Fukushima where avalanches occurred at a frequency of 6 or more per winter. For all the years covered by the survey, the total number of disastrous avalanches was 1152. About 500 avalanches killed or injured people. The number of persons killed was 800, the number injured 500. The average number of avalaches per winter was 28. Monthly peaks in these prefectures were found to occur in February with the exception of Aomori prefecture and hourly peaks occurred in mid-morning or in mid-afternoon depending upon prefectures.
