Abstract
The earthquake that occurred on March 11, 2011, off the Pacific coast of Tōhoku triggered many landslides on the natural slopes of Shirakawa Hills, Fukushima Prefecture, Japan. The landslide that occurred in Hanokidaira area caused the most damage and claimed the lives of 13 people; the failure occurred in the thick brown volcanic ash sediment layer on the hill slope and caused rapid soil flow across extensive areas, thereby increasing the resulting damage. There are a number of rapid landslides with similar characteristics even outside the Hanokidaira District; a volcanic soil layer collapsed and flowed a relatively long distance. The locations of many of these landslides are, like that in the Hanokidaira District, running from the crest slope to the upper sideslope located above a valley head and straddling knick lines. The slip surface is weathering tephra, and as in the Hanokidaira District case, presumably occurred with the part which was clay weakened by weathering.

Acknowledgments
We are grateful to Professor Takehiko Suzuki of Tokyo Metropolitan University, who kindly provided advice concerning the determination of tephra. The issues related to this study were discussed in “Identification of the status of slope movement triggered by earthquakes and the classification of features” (Contract research program for river technology development by the Ministry of Land, Infrastructure, Transport and Tourism), by the Japan Landslide Society. The laser profiler data were provided by the Ministry of Land, Infrastructure, Transport and Tourism. We would like to express our sincere thanks to all who supported this study.
