In this research seismicity parameters, repeat times and occurrence probability of large earthquakes are estimated for 35 seismic lineaments in Persian plateau and the surrounding area. 628 earthquakes of historical time and present century with MW>5.5 were used for further data analysis. A probabilistic model is used for forecasting future large earthquake occurrences in each chosen lineament....

geological studies are basic formof operations for the exploration and development of oil and gas fields.preparation of topographical and geological maps and drawingcross section from thesemaps formspart of these operations. existing lineaments in the study area are important, and should be considered in drawing the geological sections. the evaluation of wells stability is one of the important ...

Abstract: Lineaments are mapable linear surface features, which presumably reflect subsurface phenomena. The study demonstrates the use of ALOS imagery for lineament mapping for geological application. The image was enhanced and used for lineaments extraction through on-screen digitising. The extracted lineaments were evaluated against the published geological map for the study area using GIS o...

Introduction The description of a fault model includes the fault surfaces and associated tip lines, the fault network geometry, and the displacement geometry of faults. Fault surfaces are usually observed from seismic discontinuities, which include reflector breaks, flexures, and amplitude changes. These discontinuities can often have a regular appearance that corresponds to fault geometries fo...

The network of fault zones caused by vertical and horizontal tectonic displacements blocks Earth’s crust relative to each other is clearly visible on the surface in images obtained from satellite surveys. Many researchers distinguish linear annular structures among faults. Lineaments are detected as rectilinear objects with a certain spectral brightness. initial data for experimental research i...

The Quchan fault is located in Quchan - Shirvan area which is a part of Chenaran- Bojnourd plain in Kopeh-Dagh zone, NE Iran. The Quchan active fault with northwest – southeast trending is one of the most important strike-slip faults in the area which its activity led to the numerous historical and instrumental earthquakes. The Neo-tectonic activities of this fault are investigated by the drain...

Extracting fault, unconformity, and horizon surfaces from a seismic image is useful for interpretation of geologic structures and stratigraphic features. Although interpretation of these surfaces has been automated to some extent by others, significant manual effort is still required for extracting each type of these geologic surfaces. I propose methods to automatically extract all the fault, u...
