Recent deployments of dense seismic and geodetic observation networks have revealed a detailed pattern of crustal stress and strain rate in tectonically active regions all over the world. Furthermore, the M9.0 2011 Tohoku-oki earthquake provided a unique opportunity to investigate how the Japanese Islands' crust responds to instantaneous as well as transient stress changes due to the giant fault motion. With these precious observations, now is the time to proceed toward integrated understanding of dynamic processes in the Earth's crust, such as great earthquakes and various related phenomena in a variety of spatial and temporal scales. This special issue aims to bring state-of-the-art research results together to promote multidisciplinary collaborative investigation for better understanding of crustal dynamics or earthquake generation process in the island arc system.
