Scope	We explore a new perspective of great earthquakes along subduction zones by integrating results of paleoseismological surveys, variable observations, laboratory experiments, material analyses, and numerical modeling on pre- and co-seismic processes, seismic links, and the recurrence. We welcome presentations not only on great earthquakes as those along the Nankai Trough, the Sunda and Chile Trenches, etc., but also on their precursory or inducing large inland earthquakes.
