interferometric synthetic aperture radar (insar) technique is valuable tool in monitoring crustal deformation due to its large spatial coverage and high spatial resolutions. in this paper, the intersiesmic crustal deformation occurred before earthquake on august 2012 in ahar-varzegan located in north-west of iran is studied using persistent scattering interferometry. the psi algorithm used in t...

Article history: Received 7 August 2015 Received in revised form 21 January 2016 Accepted 22 January 2016 Available online 23 January 2016 In order to better understand the activity of the Akşehir normal fault in SW Turkey and the associated seismic hazard, we investigated the tectonic geomorphology of a 60-km stretch of the 100-km-long Akşehir fault block. The fault can be separated into seven...

The geometry of faults is usually thought to be more complicated at the surface than at depth and to control the initiation, propagation and arrest of seismic ruptures1–6. The fault system that runs from southern California into Mexico is a simple strike-slip boundary: the west side of California and Mexico moves northwards with respect to the east. However, the Mw 7.2 2010 El Mayor–Cucapah ear...

Although vibration monitoring is a popular method to monitor and assess dynamic structures, quantification of linearity or nonlinearity of the dynamic responses remains a challenging problem. We investigate the delay vector variance (DVV) method in this regard in a comprehensive manner to establish the degree to which a change in signal nonlinearity can be related to system nonlinearity and how...

[1] We introduce a new model which both generates a self[Stirling et al., 1996]. To get at these issues from a organizing complex segmented fault system which then theoretical point of view, we need to tackle both the issue accommodates finite strain, and generates sequences of of fault system geometry, and event dynamics, over many elastodynamic events on that complex fault system. This earthq...

The Gulf of Suez area represents one the most famous tectonic structures in Red Sea, with a long history low-, moderate-, and high-intensity earthquakes. This paper provides geomorphic analytics fault-initiated mountain front sinuosity (Smf) stream gradients that cross various segments fault scarps. results from index valley floor width to height ratio (Vf) suggest different levels activities a...

In this paper, we demonstrate a score based indexing approach for tennis videos. Given a broadcast tennis video (btv), we index all the video segments with their scores to create a navigable and searchable match. Our approach temporally segments the rallies in the video and then recognizes the scores from each of the segments, before refining the scores using the knowledge of the tennis scoring...

A high resolution DEM (1 ms spacing) derived from an airborne LiDAR campaign was 10 used in an attempt to characterize the structural and erosive elements of the geometry of the Pettino 11 fault, a seismogenic normal fault in Central Apennines (Italy). Four 90to 280 m -long fault scarp 12 segments were selected and the surface between the base and the top of the scarps was analyzed 13 through t...

[1] We discuss numerical simulations of evolving fault zone structures in a 3-D lithospheric model with a seismogenic crust governed by a damage rheology that accounts for large strain associated with permanent brittle deformation. Results for the initial propagation of an existing narrow damage zone subjected to oblique loading exhibit strong asymmetry of the evolving damage with respect to th...
