ABSTRACT
The goal of this study is to establish a numerical disaster process simulation model, which
makes it possible to estimate when the recovery from disaster will complete, what factor
accelerates physical recovery. This paper discusses about the following topics, as the first step
of this study; 1) the method to get the time series of physical recovery degree from a series of
observed images, 2) the relationship between the physical recovery degrees and behavior of
impacted people.
1. INTRODUCTION
Though seven years have passed, the reconstruction urban planning after the 1995 Kobe
earthquake is still on the way. It does not means that the quickness is the first priority in the
reconstruction urban planning. The upgrading not only in the physical level but also in the
regional economy and the community activities level are goals of the reconstruction urban
planning. However, seven years is very long time in our life.
Present reconstruction urban planning shows only the drawing of complete image. Thinking
that it takes long time to complete, not only designing the complete image but also designing
the process is necessary. Urban planning should become to have the sense of time. It says that
planner should explain what the area would become in each time phase of recovery or
reconstruction process. To do so, the simulation on disaster process of a planned area is
necessary. However, the urban reconstruction study from disaster has spotlighted to the
counter-measures or reconstruction urban planning itself until now. Even the evaluation studies
on these counter-measures are limited. So there does not exit the data sets to trace the disaster or
disaster process, which is indispensable data to make simulation.
We continue to study on "disaster process" or "recovery process" after natural disaster. The
knowledge on disaster process is constructed from the systematic knowledge on 1) variety of
problems, 2) scale of problems, 3) chronological data on each problem and 4) the
countermeasures to problems. The concept of disaster process will be shown in Fig.l. The data
on how the impacted people behaved in each phase of disaster process has been collected by the
