However,they have not been as fully investigated as landslides caused by heavy rainfall and other earthquake-induced phenomena. In order to determine the characteristics of earthquake-induced landslides in urban areas,the role of earthquake in initiating landslides is discerned after the presentation of suitable classification of landslides in Chapter 1 of this paper. It is stressed that not only the failures of artificial slopes with or without retaining walls but also slides of natural or seminatural hillslopes in and around residential districts should be considered. In Chapter 2 the method of investigation of earthquake-induced landslides is discussed. It is pointed out that official records on earthquakes often contain only insufficient information on landslides. An example of utilization of such records in the analysis of the relation between areal distribution of landslides and earthquake magnitude is demonstrated. It is also pointed out that only the root areas of slides are noted and the affected areas,where usually most damage takes place,are rather neglected in most previous scientific investigations of landslides. In conclusion,methods for investigating the future earthquake-induced landslides are proposed., postprint}, pages = {55--63}, title = {地震性斜面崩壊とその調査法について}, year = {1978} }
