Abstract
In the research of extensive and multifaceted disasters such as earthquake disasters, grasp of disaster points and damage conditions, plus the information sharing are most important. This greatly contributes to damage reduction. However, getting to the very important location sometimes becomes difficult due to by-passing sections blocked by collapses of embankments or slopes. Moreover, the drivers may be endangered by searching various signposts and disaster points. In order to ensure safe investigation, rapid location searching, recording, and information sharing, we developed a new disaster investigation support system on the basis of our experience in the research of earthquake disasters. We utilized this system for the geotechnical examination of the heavy rain in October 2006, and verified its effectiveness. The system could be employed in periodic inspection of slopes and aerial investigation.
