An attempt of extracting and sharing lessons learned from experiences of the 2011 Great East Japan earthquake disaster based on the viewpoints of experts on disaster science: The “database of lessons from March 11, 2011”

It is important to extract, clarify, and share the lessons learned from disasters to enhance preparedness for and effective responses in a disaster. This paper aims to describe the development of a web database system to share lessons learned by disaster science experts based on experiences of the 2011 Great East Japan Earthquake Disaster. First, an interview survey was conducted with local government officers in areas identified as being at risk during the Nankai Trough Earthquake to identify their needs. Next, we reported on the use of the system for three months after its release based on analyses of access log data.
