Distribution of Interseismic Coupling Along the North and East Anatolian Faults Inferred From InSAR and GPS Data [PDF]

Geophysical Research Letters, 2020
<p>The North Anatolian Fault (NAF) has produced numerous major earthquakes. After decades of quiescence, the M<span>w </span>6.8 Elazı˘g earthquake (24 January 2020) has recently reminded us that the East Anatolian Fault (EAF) is also capable of producing significant earthquakes.

Overriding Plate Deformation Controls Inferences of Interseismic Coupling Along the Himalayan Megathrust

Journal of Geophysical Research: Solid Earth
AbstractThe seismic hazard along the Himalayan arc remains a focus of discussion due to its huge potential societal impact. Taking advantage of modern, dense geodetic observations, several attempts have been made to provide a clear picture of the present‐day rate of strain accumulation caused by interseismic coupling on the Main Himalayan Thrust (MHT).

Interseismic Coupling–Based Stochastic Slip Modeling of the 1920 Ms 8.5 Haiyuan Earthquake

Seismological Research Letters, 2023
Abstract The 1920 Ms 8.5 Haiyuan earthquake was the largest rupture in China in the twentieth century; however, the coseismic slip characteristics that provide insight into fault kinematics and future seismic hazards are unknown. In this study, we employed stochastic slip modeling to explore plausible slip distributions for this ...

Interseismic coupling for the Altotiberina Fault from GPS data

Il Nuovo Cimento C, 2017
The Umbria-Marche Apennines is a region characterized by strong historical and instrumental earthquakes located in a complex tectonic framework where both extensional and compressional activities are taken up. Moreover a particular fault structure, the Altotiberina fault (ATF), seems to play an active role within this tectonic extension, even if it is ...

On factors controlling the depth of interseismic coupling on the Hikurangi subduction interface, New Zealand

Earth and Planetary Science Letters, 2009
We apply a finite difference numerical thermal model to the shallow region of the Hikurangi subduction margin, North Island, New Zealand. This subduction zone is characterised by subduction of thick and buoyant crust of the Hikurangi Plateau and along-strike variations in subduction obliquity, onshore surface heat flow (low in the south, high in the ...

Study of interseismic coupling rate of 2007 Mentawai earthquake using GNSS data

AIP Conference Proceedings, 2017
A maximum of horizontal interseismic velocity rate of SuGAr station is 0.4308 m/year at BTET Station (Siberut Island) and 0.0116 m/year at BSAT Station (Pagai Island) for the vertical component from GNSS data observation. Using the inversion calculation, this research calculated interseismic coupling rate of 2007 Bengkulu/Mentawai earthquake.

Upper plate tectonic stress state may influence interseismic coupling on subduction megathrusts

Geology, 2012
We document a correlation between along-strike variation in interseismic coupling depth on subduction interfaces, and the upper plate tectonic stress state in New Zealand, Vanuatu, and southwest Japan. Deep interseismic coupling occurs where the upper plate stress regime is contractional to transpressional, whereas a shallowing of interseismic coupling

The Impact of Viscoelastic Earthquake Cycles and Elastic Heterogeneity on Interseismic Coupling

Some of the most commonly used tools for estimating the size and spatial distribution of future megathrust earthquakes are interseismic coupling models. These models estimate the degree to which a fault is interseismically coupled (i.e., not slipping at the full plate convergence rate between earthquakes) and thus accumulating strain to be released in ...

Block Kinematics and Interseismic Coupling of Major Subduction Systems in the Central Mediterranean

The Mediterranean is a broad continental deformation zone at the junction between the African and Eurasian plates, where plate convergence is accommodated by distributed faulting, subduction, and transform systems associated with significant seismic and tsunami hazard.

Wedge geometry, mechanical strength, and interseismic coupling of the Hikurangi subduction thrust, New Zealand

Tectonophysics, 2011
The Hikurangi subduction thrust interface, east coast North Island, New Zealand, exhibits along-strike variations in seismic style: the southern segment is interseismically locked, while the plate boundary thrust slips aseismically in the north. The geometry of the offshore accretionary prism is also heterogeneous, changing from small to large taper ...
