The 1990 Rudbar earthquake (Mw 7.3) broke along three right-stepping segments of the left-lateral fault, in western Alborz mountains (Iran), producing ?80 km surface rupture. Previously reported horizontal (?60 cm) field offsets were surprisingly low, and vertical (?95 unexpected, given relatively large moment release, shallow source depth, fault geometry, rake. We characterize displacement fro...

This work proposes the segment fault protection mechanism called Non-Overlap Segment Protection (NOSP) and Overlap Segment Protection (OSP) using the method of multiple-ring search in Wavelength Division Multiplexing (WDM) mesh networks. Multiple-ring search operates in distributed control, and gathers network information through neighboring nodes. Hence, the proposed methods can be adopted in ...

Although destructive earthquakes have not occurred in the instrumental period except for 30 October 2020 Samos earthquake (Mw = 6.6), records show that there were significant caused great destruction İzmir and its surroundings historical period. However, it is yet clear which faults are causative these affecting surroundings. For this purpose, has been attempted to determine new geological, sei...

a sequence of permian rocks crops out in northwest of khur in central alborz, north of iran. this sequence consists of the dorud (asselian-sakmarian), ruteh (artinskian-murgabian) and nesen (early djulfian) formations. the ruteh and nesen formations in alborz range were deposited in a shallow marine environment of the continental margin in the paleo-tethys. the ruteh formation with a thickness ...

[1] Forecasting M 7.0 San Andreas fault earthquakes requires an assessment of their expected frequency. I used a three-dimensional finite element model of California to calculate volumetric static stress drops from scenario M 7.0 earthquakes on three San Andreas fault sections. The ratio of stress drop to tectonic stressing rate derived from geodetic displacements yielded recovery times at poin...

We present the initial results of rapid fault estimations for the 2016 Kumamoto earthquake on April 16 (Mj 7.3), and coseismic displacements caused by the two large foreshocks that occurred on April 14 (Mj 6.5) and April 15 (Mj 6.4) from the GEONET real-time analysis system (REGARD), which is based on a Global Navigation Satellite System (GNSS) kinematic positioning technique. The real-time fin...

We studied the geometry and petrophysical properties of fault core damage zones a deformation band zone in arkosic sandstones Cretaceous Antenor Navarro Formation Rio do Peixe Basin, Brazil. The present work includes results from fieldwork laboratory measurements. performed structural, geometric, permeability measurements field. These were on longitudinal scanline along 18 orthogonal scanlines ...

We study the ground motion simulations based on three finite-source models for the 2007 Mw6.6 Niigata Chuetsu-oki, Japan, earthquake in order to discuss the performance of the input ground motion estimations for the near-field seismic hazard analysis. The three models include a kinematic source inverted from the regional accelerations, a dynamic source on a planar fault with three asperities in...

(paper pages 133-156) zagros active fold-thrust belt lies on the northern margin of the arabian continental crust it is a young fold-thrust mountain belt currently shortening, thickening and uplifting as a result of the collision of the arabian and iranian plates. rethickening of crust during collisional orogenies could have been carried out by reversal of fault motion along the mesozoic normal...
