Lessons Learned from Data Management Activities after the Great East Japan Earthquake in March 2011

This paper summarizes our effort towards managing the multi-disciplinary disaster-related data from the Great East Japan Earthquake, which happened on March 11, 2011 off the coast of Northeast Japan. This earthquake caused the largest tsunami in the recorded history of Japan, killed many people along the coast, and caused a nuclear disaster in Fukushima, which continues to affect a large area of Japan. Just after the earthquake, we started crisis response data management activities to provide useful information for supporting disaster response and recovery. This paper introduces the various types of datasets we made from the viewpoint of data management processing and draws lessons from our post-disaster activities.
