Geophysical Research Letters, 2016 We inferred the rupture process of the 2015 Lefkada earthquake by combining teleseismic and near‐field strong motion data, together with static and dynamic GPS displacements. The joint inversion of all data sets revealed a relatively complex slip pattern

Multi-Segment Rupture Model of the 2016 Kumamoto Earthquake Revealed by InSAR and GPS Data
Remote Sensing, 2020 The 2016 Kumamoto earthquake, including two large (Mw ≥ 6.0) foreshocks and an Mw 7.0 mainshock, occurred in the Hinagu and Futagawa fault zones in the middle of Kyushu island, Japan.

区域宽频地震波形反演所揭示的2022年青海门源MS6.9地震震源破裂过程
Dizhen xuebao, 2023 基于有限断层模型反演方法，利用区域宽频带数据反演了2022年1月青海门源MS6.9地震的震源破裂过程，并结合地质构造与地震重定位结果判断发震断层走向。综合反演结果表明：此次地震的发震断层走向为WNW向，主要以走滑为主；破裂主要发生在震源两侧，可能存在着双侧破裂，在震后2 s和9 s出现破裂极大值，最大错动量约为1.5 m，位于深度约6 km处，发生明显破裂的深度约为16 km，地表破裂长度约20 km；此次地震释放的标量地震矩为1.23×1019 N·m，相当于矩震级MW6.7，地震能量主要在前15 ...

Coseismic slip distribution of the 1946 Nankai earthquake and aseismic slips caused by the earthquake [PDF]
Earth, Planets and Space, 2014 Coseismic slip distribution on the fault plane of the 1946 Nankai earthquake (Mw 8.3) was estimated from inversion of tsunami waveforms. The following three improvements from the previous study (Satake, 1993) were made. (1) Larger number of smaller subfaults is used; (2) the subfaults fit better to the slab geometry; and (3) more detailed bathymetry ...

A New Approach to Calculate Earthquake Slip Distributions
Eos, 2021 A transdimensional, probabilistic approach is more flexible than traditional least squares fits and provides better handling of sharply varying slip distributions.

Remote Sensing, 2018 Seismogenic fault geometry, especially for a blind fault, is usually difficult to derive, based only on the distribution of aftershocks and interference fringes of Interferometric Synthetic Aperture Radar (InSAR).

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.

The distributions of slip rate and ductile deformation in a strike-slip shear zone
Geophysical Journal International, 2002 SUMMARY A simple mechanical model and dimensional analysis are used to derive a scaling law for the partitioning between slip rate on a strike-slip fault and distributed deformation in the far-field. The depth of the fault, the distributions of stress, strain rate and slip rate are solved for a given far-field force or displacement in a 2-D medium with
