It has been known for a long time that slip accompanying earthquakes accounts for only a
fraction of plate tectonic displacements. However, only recently has a fuller spectrum of …

This paper reviews achievements and findings from studies associated with numerical
modeling of tsunami since the 2011 Tohoku earthquake, and addresses challenges for …

We develop new empirical scaling laws for rupture width W⁠, rupture length L⁠, rupture
area A⁠, and average slip D⁠, based on a large database of rupture models. The database …

Non-volcanic seismic tremor was discovered in the Nankai trough subduction zone in
southwest Japan and subsequently identified in the Cascadia subduction zone. In both …

Megasplay faults, very long thrust faults that rise from the subduction plate boundary
megathrust and intersect the sea floor at the landward edge of the accretionary prism, are …

Published areas of high coseismic slip, or asperities, for 29 of the largest Circum‐Pacific
megathrust earthquakes are compared to forearc structure revealed by satellite free‐air …

CAS3D‐2, a new three‐dimensional (3‐D) dislocation model, is developed to model
interseismic deformation rates at the Cascadia subduction zone. The model is considered a …

A new model for the shape of the Philippine Sea Plate (PSP) subducting beneath southwest
Japan was constructed by combining marine seismic survey results and seismicity data. This …

Summary The Nankai Trough is a vigorous subduction zone where large earthquakes have
been recorded with a recurrence time of 100–200 yr. The 1946 Nankaido earthquake is well …

Coseismic slip distribution on the fault plane of the 1944 Tonankai earthquake is estimated
from inversion of tsunami waveforms. Three improvements from a previous study [Satake …
