Recent geoinformatic technologies now enable us to show the historical changes of cities on digital models of the Earth, such as Google Earth, by using old maps and aerial photographs. These representations can demonstrate the post-disaster recovery processes. As a case study, this paper explains how Google Earth was used to create an urban recovery digital archive for Tokyo’s Marunouchi area that covered the period from 1907 to 2000 by applying the methodology the authors proposed in a previous research. The contents located onto Google Earth consisted of three-dimensional building diagrams, land use layers, viewpoints on earthquake vulnerability risks for building collapses, conflagration, and evacuation safety. The author used four criteria; the number of buildings, the building area, the road ratio, and the fireproof area ratio, in the analysis of the earthquake vulnerability risk transitions. First, using seven maps from 1907 to 2000, the author created land use polygon layers and analyzed the risk transitions by Geographic Information System (GIS). Second, the author constructed three-dimensional building diagrams at each point of in time using Google Sketch Up. The results were then loaded onto Google Earth and set up the urban recovery archive program so they would as they change according to timescale on the Google Earth.
