Interseismic Deformation in the Gulf of Aqaba Inferred from GPS Measurements
2020<p>The Dead Sea Transform fault forms the boundary between the Arabian plate and the Sinai-Levant subplate. Several aspects of this fault system have been extensively studied during the last century. However, the present-day kinematics and deformation along its southern end in the Gulf of Aqaba remain poorly understood.

Mechanical Models for InterSeismic Deformation in Subduction Zones
2010Traditionally, interseismic deformation in subduction zones has been modeled using simple elastic dislocation models (EDMs). Such models have been extensively used over the past couple of decades as geodetic networks were being established around the world.

Optimal combination of InSAR and GPS for measuring interseismic crustal deformation
Advances in Space Research, 2010High spatial resolution measurements of interseismic deformation along major faults are critical for understanding the earthquake cycle and for assessing earthquake hazard. We propose a new remove/filter/restore technique to optimally combine GPS and InSAR data to measure interseismic crustal deformation, considering the spacing of GPS stations in ...

Interseismic deformation in the Tjörnes Fracture Zone, North Iceland from GNSS measurements
2023The Tjörnes Fracture Zone poses significant seismic hazard to the town of Húsavík and other nearby coastal communities in North Iceland as it is capable of generating earthquakes of magnitude ~7. The 120 km long offset connects the offshore Kolbeinsey Ridge to the onshore Northern Volcanic Zone and accommodates approximately ...

Abstract Geodetic studies have shown that deformation rates around several major strike‐slip faults are asymmetric. This asymmetry is often explained in terms of a crustal‐scale contrast in elastic properties across the fault. Motivated by the fact that elasticity variations for different rock types under similar ambient conditions are generally ...

Abstract The North Tehran Fault (NTF) stands out as a major active thrust fault running for approximately 110 km north of Tehran, the capital province of Iran. It has been the source of several major historical earthquakes in the past, including those in 958, 1665, and 1830.

Abstract The deformations of the overriding and subducting plates during the seismic cycle associated with large subduction earthquakes are modelled using 2D and 3D finite element techniques. A particular emphasis is put on the interseismic velocities and on the impact of the rheology of the asthenosphere.

Abstract We make use of two-step modeling to simulate inter- and coseismic deformation within one seismic cycle by means of visco-elastic finite element method (FEM). The first step is to perform inversion to find the optimum modeling parameters by fitting the observed interseismic deformation.

A two-dimensional dislocation model for interseismic deformation of the Taiwan mountain belt
Earth and Planetary Science Letters, 2003We use a Global Positioning System (GPS)-derived surface velocity field of Taiwan for the time period between 1993 and 1999 to infer interseismic slip rates on subsurface faults. We adopt a composite elastic half-space dislocation model constrained by the observed horizontal velocities projected into the direction of plate motion (306‡).
