Coseismic sediment deformation during the 1989 Loma Prieta earthquake [PDF]

Journal of Geophysical Research: Solid Earth, 2008
Inelastic horizontal sediment deformation from the MS 7.1, 17 October 1989 Loma Prieta earthquake has been estimated to be on the order of 20 cm at a site in Gilroy, California, about 32 km east of the epicenter. This estimate was based on combined deterministic‐stochastic simulations using ground motion data and sediment properties measured from in ...

The possibility of estimating the coseismic deformation from water level observations in wells [PDF]

Izvestiya, Physics of the Solid Earth, 2010
A method for point estimation of coseismic volume deformation from amplitudes of earthquake-induced jumps in the water level and from the tidal sensitivity of the water level is presented. Application of this method is illustrated by six Kamchatka earthquakes of 1997–2004 with Mw = 6.2–7.8 that occurred 128–316 km from the YuZ-5 well.

Improved coseismic deformation detection via SBAS InSAR-Hyperbolic tangent step model integration

International Journal of Applied Earth Observations and Geoinformation
The centimeter level deformation generated by small and medium-sized earthquakes contains rich information on tectonic activity, which is of great value for improving the coseismic deformation database and fault dynamics models.

Coseismic deformation induced by the Sumatra earthquake

Journal of Geodynamics, 2006
Abstract The giant Sumatra-Andaman earthquake of December 26, 2004 caused permanent deformations effects in a region of previously never observed extension. The GPS data from the worldwide network of permanent IGS sites show significant coseismic displacements in an area exceeding 107 km2, reaching most of South-East Asia, besides Indonesia and India.

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.

Spectral-infinite-element simulations of coseismic and post-earthquake deformation

Geophysical Journal International, 2018
Accurate and efficient simulations of coseismic and post-earthquake deformation are important for proper inferences of earthquake source parameters and subsurface structure.

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 ...

Coseismic Deformation Obtained by Various Technical Methods and Its Constraint Ability to Slip Models of Maduo Earthquake

Remote Sensing
The coseismic deformation field on both sides of the fault, especially the distribution and change characteristics of near-field deformation, not only provides important constraints for the fine inversion of the slip distribution model but also serves as

Interseismic, Coseismic, and Early Postseismic Slip Associated With the 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters
Unraveling the surface deformation and fault kinematics during the seismic cycle is crucial for understanding earthquake physics. Herein, we use geodetic and seismic observations to quantify the interseismic coupling, coseismic rupture, and postseismic ...

Vector Angular Continuity in the Fusion of Coseismic Deformations at Multiple Optical Correlation Scales

Sensors, 2023
As one of the common techniques for measuring coseismic deformations, optical image correlation techniques are capable of overcoming the drawbacks of inadequate coherence and phase blurring which can occur in radar interferometry, as well as the problem ...
