Coseismic slip distribution of the 1923 Kanto earthquake, Japan [PDF]
Journal of Geophysical Research: Solid Earth, 2005 The slip distribution associated with the 1923 M = 7.9 Kanto, Japan, earthquake is reexamined in light of new data and modeling. We utilize a combination of first‐order triangulation, second‐order triangulation, and leveling data in order to constrain the coseismic deformation.

Coseismic and postseismic fault slip characteristics of the 2020 MW6.3 Nima earthquake
地球与行星物理论评, 2023 The 2020 MW6.3 Nima earthquake occurred in the northern Yibug Caka graben on the Qiangtang Block of the Tibetan Plateau. The epicentral area has complex geological structures, topography, and geomorphology, and there are few near-field ground observation

Imaging coseismic rupture in far field by slip patches [PDF]
Geophysical Journal International, 2004 SUMMARY Since the end of the 1970s, teleseismic waves are used routinely to infer the first-order characteristics of the event (location, depth, duration, focal mechanism), but finding the second-order kinematic parameters (spatial distribution of slip, rupture velocity and more basically the discrimination between the fault plane and the other nodal ...

Coseismic damage runs deep in continental strike-slip faults
Earth and Planetary Science Letters, 2020 Abstract Coseismic off-fault damage and pulverization significantly influence the mechanical and transport properties, and in turn the rupture dynamics of faults. Although field-based, laboratory, and numerical studies help elucidate the structure of damage zones adjacent to modern strike-slip faults, the vertical extent of these zones remains an ...

Constraints on fault and lithosphere rheology from the coseismic slip and postseismic afterslip of the 2006 M_w 7.0 Mozambique earthquake [PDF]
, 2012 The 2006 M_w 7.0 Mozambique (Machaze) normal-faulting earthquake ruptured an unusually steeply dipping fault plane (~75°). The amount of slip in the earthquake decreased from depths of ~10 km toward the surface, and this shallow slip deficit was at least

Coseismic Ground Deformation Reproduced through Numerical Modeling: A Parameter Sensitivity Analysis
Geosciences, 2019 Coseismic ground displacements detected through remote sensing surveys are often used to invert the coseismic slip distribution on geologically reliable fault planes.

Horizontal coseismic deformation of the 1999 Chi-Chi earthquake measured from SPOT satellite images: Implications for the seismic cycle along the western foothills of central Taiwan [PDF]
, 2003 The 1999 Chi-Chi earthquake, M_w = 7.6, broke a major thrust fault along the western foothills of the Central Range of Taiwan. We have measured the horizontal coseismic displacement field by correlating optical satellite images acquired before and after ...
