Abstract
The achievements of the “Nankai Trough Wide Area Earthquake Disaster Prevention
Research Project” commissioned by MEXT started in 2013 are described here. In the field
of disaster prevention, lessons learned from the 2011 Great East Japan Earthquake damage,
estimation with different spatiotemporal scales, and a preliminary reconstruction plan based on
future spatiotemporal changes in the social environment were studied. They were integrated
through workshops and utilized to promote the information dissemination by regional study
groups using the disaster scenarios and disaster information platform. In the field of survey,
observation, and simulation research, the seismic image on the Nankai trough with threedimensional
seismogenic zone structure and evaluation of earthquake occurrence diversity
based on advanced simulation research, tsunami history surveys, and historical literature
surveys were researched. As the result, the basic system of transition prediction was obtained.
