Variation of Fault Creep Along the Overdue Istanbul‐Marmara Seismic Gap in NW Türkiye

نویسندگان

چکیده

Abstract Strain energy from tectonic loading can be partly released through aseismic creep. Earthquake repeaters, repeatedly activated brittle fault patches surrounded by creep, indicate steady‐state creep that affects the amount of seismic available for next large earthquake along a plate contact. The offshore Main Marmara Fault (MMF) North Anatolian Zone represents gap capable generating M > 7 in direct vicinity to mega‐city Istanbul. Based on newly compiled seismicity catalog, we identify repeating earthquakes resolve spatial variability MMF during 15‐year period. We observe maximum repeaters indicating central and western segments tapering off toward locked onshore Ganos west, Princes Islands segment immediately south Istanbul east. This indicates high degree Istanbul‐Marmara gap.

Detection of fault segments based on P–T dihedra analysis along the North Tabriz fault, NW Iran

Detection of fault segments is an essential step for tracking main transverse faults. General observations from field studies as well as attitude measurements can give an overall understanding of the lengths of the segments, but these are not always sufficient to accurately identify and characterize them. In this study, we analyze P–T dihedra variations based on their eigenvalues to detect faul...

Localized and distributed creep along the southern San Andreas Fault

We investigate the spatial pattern of surface creep and off-fault deformation along the southern segment of the San Andreas Fault using a combination of multiple interferometric synthetic aperture radar viewing geometries and survey-mode GPS occupations of a dense array crossing the fault. Radar observations from Envisat during the period 2003–2010 were used to separate the pattern of horizonta...

The mafic rocks along the North Tabriz Fault, possible remnants of Neo-Tethys oceanic crust in NW Iran

The North Tabriz Fault is seismologically an active fault with current right lateral strike-slip movements. Restricted mafic to intermediate Late Cretaceous igneous rocks are exposed along the North Tabriz Fault. Whole rock samples and clinopyroxene phenocrysts geochemistry were studied in order to characterize the petrogenesis of these mafic rocks and their possible relation to an oceanic crus...

Creep along the Imperial Fault, southern California, from GPS measurements

[1] In May of 1999 and 2000, we surveyed with Global Positioning System (GPS) 46 geodetic monuments established by Imperial College, London, in a dense grid (half-mile spacing) along the Imperial Fault, with three additional National Geodetic Survey sites serving as base stations. These stations were previously surveyed in 1991 and 1993. The Imperial College sites were surveyed in rapid-static ...

Post-seismic and interseismic fault creep I: model description

S U M M A R Y We present a model of localized, aseismic fault creep during the full interseismic period, including both transient and steady fault creep, in response to a sequence of imposed coseismic slip events and tectonic loading. We consider the behaviour of models with linear viscous, non-linear viscous, rate-dependent friction, and rateand state-dependent friction fault rheologies. Both ...
