Coseismic Rupture and Postseismic Afterslip of the 2020 Nima Mw 6.4 Earthquake

Remote Sensing
On 22 July 2020, an Mw 6.4 earthquake occurred in Nima County in the Qiangtang Terrane of the central Tibetan Plateau. This event, caused by normal faulting, remains controversial in terms of its rupture process and causative fault due to the complex ...

The spatial response pattern of coseismic landslides induced by the 2008 Wenchuan earthquake to the surface deformation and Coulomb stress change revealed from InSAR observations

International Journal of Applied Earth Observations and Geoinformation, 2020
The 2008 Mw 7.9 Wenchuan earthquake triggered plenty of coseismic giant landslides, which resulted in almost one third of total fatalities and economic losses during the event.

Seismogenic, coseismic and postseismic deformation and stress evolution of the 2008 Wenchuan earthquake: Numerical simulation analysis

Dizhi lixue xuebao, 2021
The 2008 MS 8.0 Wenchuan earthquake occurred in the Longmenshan fault zone, which has complex geological background, strong surface relief, and heterogeneous elastic-viscous structures; however, the seismic risk of the Longmenshan fault zone was ...

Source parameters of the great Sumatran megathrust earthquakes of 1797 and 1833 inferred from coral microatolls [PDF]

, 2006
Large uplifts and tilts occurred on the Sumatran outer arc islands between 0.5° and 3.3°S during great historical earthquakes in 1797 and 1833, as judged from relative sea level changes recorded by annually banded coral heads.

Measuring Coseismic Deformation With Spaceborne Synthetic Aperture Radar: A Review [PDF]

Frontiers in Earth Science, 2019
In the past 25 years, space-borne Synthetic Aperture Radar imagery has become an increasingly available data source for the study of crustal deformation associated with moderate to large earthquakes (M > 4.0). Coseismic surface deformation can be measured with several well-established techniques, the applicability of which depends on the ground ...

Global coseismic deformations, GNSS time series analysis, and earthquake scaling laws [PDF]

Journal of Geophysical Research: Solid Earth, 2014
AbstractWe investigate how two decades of coseismic deformations affect time series of GPS station coordinates (Global Navigation Satellite System) and what constraints geodetic observations give on earthquake scaling laws. We developed a simple but rapid model for coseismic deformations, assuming different earthquake scaling relations, that we ...

Newly Discovered Active Faults in the Wairarapa Valley: Implications for Multi‐Fault Rupture and Kinematics in the Southern North Island, Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Active fault locations and constraints on the timing and size of earthquakes are important for understanding and mitigating seismic hazard in Aotearoa New Zealand. However, historical and instrumental records are too short to provide these data on most earthquake‐generating faults. Light detection and ranging (lidar) data provide us with the ability to

Large‐Scale Deformation, Strain Characteristics, and Locking Distribution of the Qilian‐Haiyuan Fault System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The Qilian‐Haiyuan fault system is the main tectonic boundary of the northeastern Tibetan Plateau, controlling the regional tectonic deformation and seismic activity. Extensive Sentinel‐1 SAR data (2014–2021) are used to map the regional tectonic deformation, strain distribution, and locking along primary and secondary faults.

Coseismic and postseismic deformation associated with the 2016 Mw 7.8 Kaikoura earthquake, New Zealand: fault movement investigation and seismic hazard analysis

Earth, Planets and Space, 2018
The 2016 moment magnitude (Mw) 7.8 Kaikoura earthquake demonstrated that multiple fault segments can undergo rupture during a single seismic event. Here, we employ Global Positioning System (GPS) observations and geodetic modeling methods to create ...

On the evolution of elastic properties during laboratory stick-slip experiments spanning the transition from slow slip to dynamic rupture [PDF]

, 2016
The physical mechanisms governing slow earthquakes remain unknown, as does the relationship between slow and regular earthquakes. To investigate the mechanism(s) of slow earthquakes and related quasi-dynamic modes of fault slip we performed laboratory ...
