Recent Crustal Deformation in West-Central South America [PDF]

, 2003
I use interferometric synthetic aperture radar (InSAR) to create maps of crustal deformation along the coast and within the volcanic arc of central South America. I image deformation associated with six subduction zone earthquakes, four volcanic centers,

Rupture Kinematics and Coseismic Slip Model of the 2021 Mw 7.3 Maduo (China) Earthquake: Implications for the Seismic Hazard of the Kunlun Fault

Remote Sensing, 2021
The 21 May 2021 Maduo earthquake was the largest event to occur on a secondary fault in the interior of the active Bayanhar block on the north-central Tibetan plateau in the last twenty years.

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 ...

Coseismic recrystallization during shallow earthquake slip [PDF]

, 2013
seismic slip in the geological record. However, pseudotachylytes form at >5 km depth, and there are many rock types in which they do not form at all. We performed low- to high-velocity rock friction experiments designed to impose realistic coseismic slip

Coseismic fault model of the 2017 MW 6.5 Jiuzhaigou earthquake and implications for the regional fault slip pattern

Geodesy and Geodynamics, 2022
On August 8, 2017, an MW 6.5 earthquake occurred in Jiuzhaigou County, Sichuan Province, China, on the eastern margin of the Qinghai–Tibet Plateau. This study investigates the coseismic deformation field and fault model with ascending and descending ...

Coseismic and initial postseismic slip of the 2009 Mw 6.3 l’Aquila earthquake, Italy, from GPS measurements [PDF]

, 2010
Here we report the preliminary results of GPS data inversions for coseismic and initial afterslip distributions of the Mw 6.3 2009 April 6 L’Aquila earthquake.

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.

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 ...

Automated fault model discretization for inversions for coseismic slip distributions [PDF]

Journal of Geophysical Research: Solid Earth, 2010
Geoscientists increasingly rely on coseismic slip distributions inferred from geodetic observations to drive sophisticated models of the seismic cycle. To date, little work has been done on optimizing the parameterization of these fault models so that they reflect the resolving power of observed surface displacements.

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.
