Abstract
 Real Time Landslide Disaster System in Yokohama, Japan Track: Disaster Mangagement and Emergency Response Author(s): Keiko Inagaki, Satoru SADOHARA In Japan, landslides must be measured where they often occur. Recent efforts to develop soft-measures are underway because hard-measures, like covering hillsides with concrete, create economical and environmental problems. This paper will demonstrate how municipal governments can use ArcGIS to manage landslides. Areas prone to landslides are identified using ArcGIS and rainfall data. Also, a database system using ArcGIS Server and ArcSDE was developed to combine spatial data with existing data about potential landslides. The steep slopes in Yokohama city are used as objects of this study. This method is applicable to all Japan because all local governments have the same inspection records and are making various spatial data based on 'e-government' policy. This paper will also show how to use existing inventory data on steep slopes, records of past landslides, rainfall data and DEM to manage landslides.
