Guilan is a northern province of iran which its important capital city , rasht is located in southern side of caspian sea . The result of this analysis is preparation of vertical and horizontal spectral acceleration maps with exceeding probability of 2 and 10 percents in a 50 year life cycle and 5 percents of damping for 16 different periods which can support gilan from east to west and south . utilizing these maps vertical and horizontal components of uniform seismic hazard spectra for cities of rasht anzali fooman , lahijan , roodbar and manjil for exceeding probability of 2 and 10 percents in a 50 year life cycle is presented.
