Recurrence of postseismic coastal uplift, Kuril subduction zone, Japan
نویسندگان
چکیده
[1] Coastal stratigraphy of eastern Hokkaido indicates that decimeters of coastal uplift occurred repeatedly in the late Holocene. Employing radiocarbon dating and tephrochronology, we identify along a 100 km length of the Kuril subduction zone six uplift events since 2,800 years B.P. Uplift events occur at the same frequency as unusually high tsunamis. Each coastal uplift event, which occurs on average every 500 years, is the product of decade-long post seismic deep slip on the down dip extension of the seismogenic plate boundary following an offshore multisegment earthquake that generates unusually high tsunamis.

The development of a diatom-based transfer function along the Pacific coast of eastern Hokkaido, northern Japanâ•flan aid in paleoseismic studies of the Kuril subduction zone
This paper provides a dataset to develop a diatom-based transfer function, which is applicable to paleoseismic studies at southwestern Kuril subduction zone, northern Japan. Modern diatom samples were collected from five transects from saltmarshes of Lakes Akkeshi and Onnetoh along the Pacific coast of eastern Hokkaido. The relationships between diatom species and environmental variables were e...
متن کاملContributions of poroelastic rebound and a weak volcanic arc to the postseismic deformation of the 2011 Tohoku earthquake
A better understanding of fluid-related processes such as poroelastic rebound of the upper crust and weakening of the lower crust beneath the volcanic arc helps better understand and correctly interpret the heterogeneity of postseismic deformation following great subduction zone earthquakes. The postseismic deformation following the 2011 Mw9.0 Tohoku earthquake, recorded with unprecedented high...
متن کاملAnisotropy and Flow in Pacific Subduction Zone Back-arcs
We have obtained constraints on the strength and orientation of anisotropy in the mantle beneath the Tonga, southern Kuril, Japan, and Izu-Bonin subduction zones using shear-wave splitting in S phases from local earthquakes and in teleseismic core phases such as SKS. The observed splitting in all four subduction zones is consistent with a model in which the lower transition zone (520–660 km) an...

متن کاملHomogeneous vs heterogeneous subduction zone models Coseismic and postseismic deformation
A finite-element model (FEM) incorporating geologic properties characteristic of a subduction zone is compared with FEMs approximating homogeneous elastic halfspaces (HEHS)s to investigate the effect of heterogeneity on coseismic and postseismic deformation predictions for the 1995 Colima-Jalisco M•o=8.0 earthquake. The FEMs are used to compute a coefficient matrix relating displacements at obs...
