Great (M∼ 8) earthquakes repeatedly occur along the subduction zones around Japan and
cause fault slip of a few to several metres releasing strains accumulated from decades to …

This paper reviews recent progress in tsunami geology and the history of coastal
uplift/subsidence along the Pacific coasts of Hokkaido and Tohoku, facing the Kuril and …

Numerical modelling of transoceanic tsunami propagation, together with the detailed
modelling of inundation of small-scale coastal regions, poses a number of algorithmic …

The Pacific plate converges with northeastern Eurasia at a rate of 8–9 m per century along
the Kamchatka, Kuril and Japan trenches. Along the southern Kuril trench, which faces the …

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 …

On September 26, 2003, a large earthquake with a magnitude of 8.0 occurred along the
Kuril trench off Tokachi, Hokkaido, Japan. We investigated the source process by using …

Mud volcanoes sometimes erupt within days after nearby earthquakes. The number of such
nearly coincident events is larger than would be expected by chance and the eruptions are …

In eastern Hokkaido, 60 to 80 kilometers above a subducting oceanic plate, tidal mudflats
changed into freshwater forests during the first decades after a 17th-century tsunami. The …

We have developed a new method for inverting tsunami waveforms that reveals
considerable detail in megathrust slip during subduction zone earthquakes. Previous …

The role of seafloor roughness on the seismogenic behavior of subduction zones has been
increasingly addressed over the past years, although their exact relationship remains …
