3. Accumulation and Provision of Information on Natural Disasters and Disaster Reduction

3-6. Disaster Analysis Based on Satellite Information
Tens of satellites equipped with sensors are continually observing the earth at various
wavelength, observation ranges, resolution powers and observation cycles, and some of theimage data collected by these satellites are open to the public. Making the best use of satellite
information facilitates effective disaster reduction activities such as analysis and forecasts ofdisasters (see Table 3-6-1).

With an aim to encourage the use of satellite information among the disaster reduction
personnel of the regional or local governments and individual residents by disseminating theknowledge on the satellite remote sensing technology, the Disaster Reduction Working Groupof the Satellite Remote Sensing Promotion Committee, Remote Sensing Technology Center(RESTEC), put together a guidebook of disaster analysis in 2000. This guidebook“Introduction of disaster analysis methods using satellite information” (in Japanese only)
explains the procedure using case reports of satellite data analysis conducted for actual disasters
as examples. This book is available on http://www.restec.or.jp/eeoc/bousai/v11.htm. As shownin Fig, 3-6-2, the website has information of various cases and is designed for ease of search andselection by analytical method, time period, cause of disaster, location or area of occurrence,satellite and sensor.
Fig. 3-6-2

Cases by location of disaster occurrence

In addition to the text information, a lot of flowcharts and data used for analysis including
image data are linked to the guidebook for ease of understanding how to use satellite data (seeFig. 3-6-3).

This education effort is considered to be valuable for all researchers and administrative
personnel in charge of disaster reduction not only in Japan but also in all Asian countries.
ADRC acquired the right to create and open to public an English version of the web pages inorder to contribute to the promotion of disaster reduction activities in member countries. ADRC
will be continuously accumulating the case reports of disaster-related researchers for moresophisticated database of disaster analysis methods using satellite information(http://www.adrc.or.jp/dmweb/index.html, English only).
