Review the Seismic Activity and the Signs Indicate the Volcanic Activity in Taftan Volcanic Region

To review the activities of Taftan volcano and indicating its relationship with seismicity of the region, by considering the conducted works relatively similar with our considered subject in the world, requires to study the seismicity parameters of the area at volcano occurrence time and all the under study time interval. The required data, after collecting and compiling seismic and Taftan volcano events’ catalogue from the sites and reliable centers in the world, were integrated and by using reliable existing formulas of seismic of the area at the occurrence time of each volcanic event were studied and analyzed.In this study, while preparing a catalog of the reordered seismicity and volcanic activities in the area, it is tried to evaluate the effects of its current activities on its seismicity. Combining the obtained information and general conclusion, showed no special abnormality about this volcano, but the analysis of the current seismic data of Taftan area, represents Gutenberg - Richter relationship as log N=-0.3975 M+2.7489, which the peak seismic activity of Taftan area has been during years 1990- 1994. The information about volcanic activities in the region is not enough, however between volcanic activities of years 1902.1970 and 1993 with seismic activity, a time relationship can be observed. Therefore, with respect to the importance of Taftan region from the view point of natural hazards and lack of existing information for the required studies, comprehensive tectonic seismic monitoring of Taftan area and volcano seems necessary.
