Abstract:
ان الهدف الاساسي من اعداد هذه الدراسة هو تحديد التوزيع المكاني للهزات الارضية في منطقتي (واسط وميسان) والواقعة بين خطي طول (45,35 - 47,57) ودائرتي عرض (31,12 - 33,30) وللفترة (1980 - 2013م), ورسم خرائط للمناطق التي يتركز فيها النشاط الزلزالي من اجل رمفد المسؤو | The main objective of the preparation of this study is to determine the spatial distribution of the earthquakes in the regions of ( wasit and masyan) which are located between longitudes (45.35 - 47.57) and latitudes (31.12 - 33.30) for the period - 1980 to 2013 and the map of areas in which is evident the seismic activity in order to provide accurate planning with seismic information for the study area to take the necessary measures when developing special designs for any engineering establishment.The seismic historical data were analyzed for the period from (839 - 1979) which have collected from various sources where it is noticed that western Iran area and Wasit goverorate recorded the highest seismic movement on a scale Mrkala reaching 7 - 8 degrees in the years( 839 - 849 - 872 - 880 - 956 - 957 - 1052 - 1063 ) additionally most of the historical earthquakes are of seismic surface foci - 27 - 33 km and it highly effective.The seismic modern data were analyzed for the period of 1980 - 2013 they were divided into two periods the first is from ( 1980 to 2004) and the second from (2005 to 2013) they have been recorded 824 different magnitudes earthquake on Richter scale, (69) earthquakes for the first period and 695 earthquakes for the second period. It sample survey method is used in order to collect the required information by witnesses form of and (350) forms distributed over the study area (240) forms were wasit and (110) forms for masyan area in order to compare the feeling of people in those areas on Markali scale with (semis amount) on the Richter scale to earthquake occurred in 22 /11/2 013 and the result was the feeling of Ali Al - Garbi people was 77 degrees on a scale Markali and it equal - 5,5 - 6,1 - degree on Richter scale.Badrah district , came after it where their sense of 6 degree on Markali scale and equivalent to 4,9 - 5,4 on Richter scale the less area feeling with earthquake is the center of Kut district whose feeling is( 3) degrees on a scale Markali which is equivalent to 4,2 degrees on Richter scale followed by center amarah district whose feeling was (2) degrees on a scale of Markali which is equivalent to 3,5 degrees on Richter scale.The study arrived to map the seismic division of the study area, which describes the areas more vulnerable to earthquake west of Iran, which is the borderline between Iraq and Iran area Badrha - Ali Gharbi area. - In order to predict future seismic hazard was applied equation (Seismic prediction equation was) for the period from 2014 - 2030 and the result was the continuation of seismic activity in the region where an earthquake will reach 1622,187. The study came up with some recommendations to take the necessary measures in the future.
