Project outline & field work
The east coast of Japan is prone to tsunamigenic earthquakes, as tragically demonstrated on 11 March 2011 by the Tohoku-oki earthquake (Mw 9.0) and tsunami. The Nankai subduction zone, to the southwest of the area affected by the Tohoku-oki disaster and facing the densely populated and heavily industrialised eastern coastline of Central and West Japan, is expected to generate another megathrust earthquake and tsunami in the near future.
The QuakeRecNankai (QRN) project aims to reconstruct past earthquakes along the Nankai Trough. The project combines field work in lakes and coastal lowlands, advanced sedimentological and geochemical analyses, innovative dating techniques, tsunami inundation modelling and hazard assessment, with government policy support and public outreach. The project unites a consortium of international experts, including Belgian teams from Ghent University, the Royal Belgian Institute of Natural Sciences and the University of Liège who provide expertise in paleotsunami and paleoseismological research, two Japanese teams from AIST and Tokyo University, with expertise in paleotsunami and limnogeological research, and a team from Cologne University with expertise in tsunami-deposit dating.
