Effects of Fault Roughness on Coseismic Slip and Earthquake Locations

Journal of Geophysical Research: Solid Earth, 2019
AbstractFault zone structure is well known to exert strong controls on earthquake properties including coseismic slip distribution, rupture propagation direction, and hypocenter location. It has also been well established that the principal slip surface, which accommodates the majority of earthquake displacement, exhibits roughness at all scales ...

Coseismic Kinematics of the 2023 Kahramanmaras, Turkey Earthquake Sequence From InSAR and Optical Data

Geophysical Research Letters, 2023
We derive the ALOS‐2 coseismic interferograms, pixel‐offsets and Sentinel‐2 sub‐pixel offsets of the 2023 Mw7.8 and Mw7.7 Kahramanmaras, Turkey earthquake sequence.

Preceding, coseismic, and postseismic slips of the 2011 Tohoku earthquake, Japan [PDF]

Journal of Geophysical Research: Solid Earth, 2012
We estimated the spatial and temporal evolution of the preceding aseismic slip from January 2003 to January 2011, the coseismic slip of the Tohoku earthquake, and the postseismic slip after the earthquake based on global positioning system (GPS) data. Time‐dependent analysis indicates aseismic slip offshore of Miyagi and Fukushima prefectures from 2004

Co- and post-seismic slip analysis of the 2017 MW7.3 Sarpol Zahab earthquake using Sentinel-1 data

Geodesy and Geodynamics, 2022
The MW7.3 Sarpol Zahab earthquake that occurred in the Zagros Fold-Thrust Belt (ZFTB) of Iran on November 12, 2017 is the largest earthquake instrumentally recorded in the region.

Coseismic and early postseismic deformation of the 2020 Nima Mw 6.4 earthquake, central Tibet, from InSAR and GNSS observations

Frontiers in Earth Science, 2023
The 2020 Mw6.4 Nima earthquake is one of the largest normal-faulting earthquakes recently occurring north of the Banggong suture zone in remote central Tibet, where geologic investigation of active faults is extremely limited.

Coseismic deformation of the ground during large-slip strike-slip ruptures: Finite evolution of “mole tracks” [PDF]

Geosphere, 2021
Abstract To evaluate ground deformation resulting from large (~10 m) coseismic strike-slip displacements, we focus on deformation of the Kekerengu fault during the November 2016 Mw 7.8 Kaikōura earthquake in New Zealand. Combining post-earthquake field observations with analysis of high-resolution aerial photography and topographic ...

Wenchuan Ms8.0 earthquake coseismic slip distribution inversion

Geodesy and Geodynamics, 2015
AbstractBy using GPS and gravity data before and after the Wenchuan Ms8.0 earthquake and combining data from geological surveys and geophysical inversion studies, an initial coseismic fault model is constructed. The dip angle changes of the fault slip distribution on the fault plane are inversed, and the inversion results show that the shape of the ...

New constraints on the uplift of October 9, 1995 Jalisco-Colima earthquake (Mw 8) based on the analysis of tsunami records at Manzanillo and Navidad, Mexico [PDF]

Geofísica Internacional, 2000
Tsunami records registered during the October 9, 1995 Jalisco-Colima earthquake (Mw 8) by two tide gauges and one pressure gauge are analyzed to estimate the coseismic subsidence at Manzanillo and Navidad Bay.

Continuous estimation of coseismic and early postseismic slip phenomena via the GNSS carrier phase to fault slip approach: a case study of the 2011 Tohoku-Oki sequence

Progress in Earth and Planetary Science, 2022
The transition process from coseismic to early postseismic phenomena within a half-day remains a significant topic for understanding the slip budget and friction properties of the fault.

Coseismic Rupture Behaviors of the January and March 2022 M_W > 5.5 Hala Lake Earthquakes, NE Tibet, Constrained by InSAR Observations

Remote Sensing, 2023
On 23 January and 25 March 2022, two MW > 5.5 Hala Lake earthquakes characterized by right-lateral strike-slip faulting occurred around the Elashan Fault in Northeastern Tibet, marking the two largest events since the 1927 MW 6.2 Hala Lake earthquake ...
