The 2011 Tohoku-oki earthquake occurred on an unexpected scale, which made us realize that the generation mechanisms of earthquakes are poorly understood. To provide a unified view of the geodynamic processes including earthquake generation processes in the Japanese arc–trench system, it is necessary to clarify the absolute values of crustal stresses, the stress–strain field, and the basic properties of the island arc crust and mantle, such as viscosity and frictional coefficients along major faults. This special issue covers all disciplines concerning the crustal dynamics of arc–trench systems and other tectonic settings: seismic and geodetic observations, geomorphology, natural and experimental rock deformation research, geofluids, and numerical simulations of crustal deformation and earthquake generation.

    Anelastic properties beneath the Niigata–Kobe Tectonic Zone, Japan

    We estimate the three-dimensional (3D) P-wave attenuation structure beneath the Niigata–Kobe Tectonic Zone (NKTZ), central Japan, using high-quality waveform data from a large number of stations. The obtained ...
