Relationship Between Lineaments Identified on Space Images and Epicenters: Case Study Arabian Rift Zone

Dr. Eng. Mohamad Rukieh
the Director General of the General Organization of Remote Sensing in Syria



Introduction
The continued research many years ago in dangerous seismic regions and active tectonic zones, pointed out, the large benefit and wide use of space images with multi scales and bands, the small, medium and large scales images used after their processing with the help of other data in solving many problems related to the studies and predicting of earthquakes.

The relationship between lineaments, faults and epicenters
In this study we will focus on the relationship between remote sensing data and epicenters. As it has become evident that most epicenters are found a long the lineaments identified on space images, or along their zones or blocks which they boundared, or in the intersection points of different tectonic displacements.
Landsat images are excellent for recognizing the continuity and regional relationships of faults; the reviewed stereo scopically is ideal for mapping these features.
The relationships between faulting and earthquakes in southern California were noted by Allen 1975. the Landsat imagery of California and the map of Margo geologic faults visible on this image along which movement is known to have occurred, show these relationships. (Fig1,a,b)

The well-known sanandreas fault that bisects this image is nearly 1000km long. The San Francisco earthquake of 1906 and others occurred because of movement along this fault, the several solid dots shown in the map are the centers of earthquakes of magnitude. (Fig 1,a).
