The problem of optimum distribution of seismic observation points here discussed is what will be the best location for the new station which is to be set up in addition to the present ones in Yugoslavia. An epicenter was assumed and then the errthquake parameters were calculated using the data of arrival times of the present eight stations which are not without a certain amount of observation errors. If the observation error is normally distributed and has a standard deviation 0.1 sec the average value of the expected errors for the epicenter location and the origin time are about 3.1km and 0.77 sec respectively. Then a new station and its location was changed uniformly with a constant stepping within the territory of Yugoslavia. If an adequate location is chosen for the additional station, the average values of expected errors all over the country decrease as much as 20%. In this way the optimum location of the new station was discussed, the calculation being based on the Monte Carlo method.ユーゴスラヴィアには現在8個の地震観測所があるが(第1表および第1図参照),さらに新しく一つの観測所を建設しようとの計画がある.その位置をどこにとつたならもつとも有効であるか,という問題を,以前からとつていると同様のシミュレイションの方法によつて考えてみた.
