The object of our Project is to setup some seismic stations within the surroinding of Ankara to measure weak and strong motion of the earth and to measure the acceleration of the earth which becomes during the quake, to determine the force which is able to give disaster to the buildings. Then by collecting the necessary datas to improve the techniquies of constructing earthquake-resistant building. Another aim of this Project is to look over the behaviour of Ankara and its surrounding for earthquakes in detail to detect the location, magnitude of quake and mechanism of fault etc. To find out characteristics of faults like species lenght, depth, absolute frequency, the magnitude occurred in the past to observe the species lenght, depth, absolute, frequency.
