Abstarct: Damavand city is located at 70 kilometer northeast of Tehran which has high migration potential; therefore it requires special attention in urban development issues. For this, the seismicity and seismic risk analysis of this city has been investigated. Areas which have been studied consist of a circle with radius of 150 kilometer to the center of Damavand city. The Alborz sedimentary structural zone has formed the major part of this area. Generally, 20 main active faults can be recognized within this area. The North Alborz fault, Caspian fault, and Mosha fault are the greatest faults in the region and since structural, lithological and consequently seismic and geophysical properties of a long fault zone are not usually uniform throughout their entire length, so fragmentation of these faults were performed to implement the accurate relevant calculation. Totally, 17 historical earthquakes and 412 earthquakes were collected with a torque magnitude of more than 3 magnets from the 3rd century BC until 2017, regardless of the associated events in the catalog. In order to remove the pre-seismic and aftershock from the catalog, the Gardner and Knopoff’s time-distance windows method has been used in the ZMAP software. Seismic parameters in the region were calculated manually and via the Kjko-Selvol software using the Gutenberg-Richter and Kjko-Selvol methods. The maximum observed magnitudes in the region is Mw =7.7 Richter and the calculated Mmax is Mw = 8.14±0.48 Richter. Considering structural and seismic factors, 7 seismic springs within this area were specified so that the seismic parameters were calculated for each one, individually. The region's acceleration map is baxsed on the earthquake hazard analysis method of the Crisis 2007 software, due to the maximum magnitudes assigned to each of the faults and their minimum distance to the center of Damavand city as well as valid decreasing relationships. In terms of seismicity calculations, Masha fault is considered as the most vibrational fault in the region. Also, in the earthquake risk analysis calculation, Masha fault with minimum distance from Damavand city produces the highest horizontal acceleration for it, which reaches to 0.32 of gravitational acceleration. Finally, the earthquake hazard zonation map was drawn up baxsed on the earth horizontal acceleration for the studied area and also the two calculated levels of seismic design, DBE 64% and MCE 10%, for the studied area respectively are 7 and 7.9 Richter for the useful life of 50 years and 7.4 and 8 Richter for 100 years.
