Abstract

Physical expansion of Tabriz metropolitan increases the possibility of earthquakes risks. Given the importance of this issue, this research is trying to pay to monitor the activities and seismic potential of Tabriz fault and the estimates of casualties in Tabriz metropolitan using remote sensing and GIS techniques. To achieve this goal, ASTER satellite image was processed in ENVI 5.3 software. Fault seismic potential is determined with empirical models and average calculations were used as the basis for assessment. The casualties are determined in accordance with the terms of seismicity and structure of our country urban elements, respectively. Based on visual interpretation of satellite data, along Tabriz fault are exposed geomorphic changes that reflect the tectonic activity is in the range of Tabriz metropolitan. Tabriz fault evidences examples of diversion of watercourse Ajichai, cliffs and lens shape phenomenon are most important that have been considered in the interpretation of the activities on satellite images. Based on empirical models, be created in Tabriz fault earthquakes is average of magnitude 6.8 on the Richter scale. Assuming earthquake seismic activity according to Tabriz fault scenario, the total population of about 1605884 of the Tabriz metropolitan was estimated approximate number 1252589 casualties consist of 658412 people dead and 594177 people injury at night
