In this paper, an original approach for analyzing Interferometric Synthetic Aperture Radar (InSAR) time series is presented and applied to the monitoring of creep along a major active fault. InSAR data are computed from satellite acquisitions and allow ground deformations occurring between different dates to be measured with high precision over large areas. However, measurement precision remain...

Morphotectonic investigations were carried out by the use of morphometric indices which serve as a tool of identification in regions with active tectonic warp. Landforms in active deformation area are produced from relations of tectonic and surficial processes. One of the most significant landforms underground is rivers that are extremely responsive to tectonic movements mainly uplift and tilti...

[1] Fluid distribution in convergent margins is by most accounts closely related to tectonics. This association has been widely studied at accretionary prisms, but at half of the Earth’s convergent margins, tectonic erosion grinds down overriding plates, and here fluid distribution and its relation to tectonics remain speculative. Here we present a new conceptual model for the hydrological syst...

Many natural examples of complex joint and vein networks in layered sedimentary rocks are hydro-fractures that form by a combination of pore fluid overpressure and tectonic stresses. In this paper, a two-dimensional hybrid hydro-mechanical formulation is proposed to model the dynamic development of natural hydrofractures. The numerical scheme combines a Discrete Element Model (DEM) framework th...

Monitoring of active faults in urban areas is of great importance, providing useful information to assess seismic hazards and risks. The present study concerns the monitoring of the potential ground deformation caused by the active tectonism in the cities of Patras and Pyrgos in Western Greece. A PS interferometric analysis technique was applied using a rich data–set of ERS–1 & 2 SLC images. Th...

A continuous GPS array is a very useful tool for monitoring and modeling crustal activity. GPS observation has revealed various unknown aspects of tectonic deformation in Japan and other locations. Quasi-real time data acquisition and dense spatial coverage enable incorporation of GPS data into simulation models for crustal activity forecast, which is similar to data assimilation in weather for...

The current geological and tectonic setting of Iran is due to the ongoing convergence between the Arabian and Eurasian Plates, which resulted in the formation of the Iranian plateau, mountain building, extensive deformation and seismicity. The Iranian plateau is characterized by various domains including the continental collision and the oceanic plate seduction. Based on S receiver functions ar...

SAR Interferometric (InSAR) techniques are widely applied for analyzing geophysical and tectonic deformations and for improving modeling techniques, with the benefits of surface deformation measurements covering areas from several to a hundred kilometers in size with a satisfactory accuracy (theoretically in the millimeter range). Nevertheless the accuracy and availability of deformation measur...
