Electric potential changes prior to shear fracture in dry and saturated rocks [PDF]

, 1998
Electric potential changes before shear rupture were measured using Darley Dale sandstone (quartz-rich) and Icelandic basalt (quartz-free) on both dry specimens and in the presence of pore fluid.

Coseismic displacement field and slip distribution of the 2005 Kashmir earthquake from SAR amplitude image correlation and differential interferometry

, 2013
International audienceThe coseismic surface displacement field and slip distribution at depth due to the Kashmir earthquake (Mw = 7.6, 2005) have been analysed by different authors using subpixel correlation of synthetic aperture radar (SAR) images and ...

Coseismic Offsets due to Intermediate Depth 16 April 2013 Southeast Iran Earthquake (M-w 7.8)

, 2014
The 16 April 2013 southeast Iran earthquake (M-w 7.8) is the second major earthquake in the region, including the Makran subduction zone, since 1945. This intraslab earthquake, within the subducting Arabian plate, occurred as a result of normal faulting ...

Joint Inversion of InSAR and Seismic Data Unveiling the Dynamic Rupture Process and Seismotectonic Kinematics of the 2023 Mw 6.8 Morocco Earthquake

Remote Sensing
On 8 September 2023, an Mw 6.8 earthquake struck the High Atlas Mountains in western Morocco, where the tectonic regime has been poorly investigated due to its remoteness and weaker seismicity compared to the northern plate boundary.

Spatial Inference of Coseismic Slip on the Cascadia Subduction Zone [PDF]

Statistisk inferens rundt store historiske jordskjelv er et viktig steg for å forstå risikoen ved fremtidige potensielle jordskjelv. I Cascadiaregionen, ved Stillehavskysten av Nord-Amerika, ble den siste fullstendige forkastningen dannet år 1700.

Limited Shallow Slip in the 1938 MS 8.3 Alaska Peninsula Earthquake Rupture

Geophysical Research Letters
The 1938 MS 8.3 and 2021 MW 8.2 earthquakes both ruptured within the Semidi segment of the Aleutian‐Alaska subduction zone. The large‐slip distribution of the 2021 event is well constrained within the depth range 25–45 km, with seaward tsunami ...

Impact of topography on coseismic modeling and earthquake static slip inversions

, 2020
After an earthquake occurs, slip models of the event may be produced by inverting geodetic data for slip on a finite fault. This process generally requires coseismic Green's functions, which must be calculated in advance.

Regularized Inversion of Coseismic Slip Distribution Based on Smoothness-Constrained Model

Advances in Geosciences, 2017
同震滑动的空间分布估计问题是不适定的，其反演结果存在非唯一性。为了获取稳定的同震滑动分布，本文采用了光滑模型约束的正则化反演方法。算法实施过程中，构建了断层面非均匀离散的滑动量分布光滑约束模型，并设计一种快速稳定的正则化因子求取方法；为了获得合理的滑动分布，采用了非负最小二乘求解方法。理论均匀滑动分布模型的反演试算，验证了反演算法的有效性和稳定性，且非负最小二乘方法能规避不合理的滑动分布。利用光滑约束反演方法反演了2005年Nias地震的同震滑动分布，并与前人的研究结果进行了对比分析。2005年Nias地震反演结果显示：断层面最大滑动量为12.8 m，这与Konca等反演得到的结果一致，且滑动分布所释放的地震矩为9.91 × 1012 Nm，其地震震级为Mw = 8.6，与USGS公布的结果一致 ...
