This study aims to analyze the statistics and to know the state seismisity Bengkulu province which includes the level of earthquake activity, earthquake distribution patterns, the index seismisity, return period of earthquakes and earthquake risk level for period 1971-2011 in Bengkulu Province. The data used from BMKG Kepahiang Bengkulu and magnitude of scale ≥ 5.0 at a depth of shallow and intermediate earthquake at the coordinates of 20 LS-50 LS and 1000 BT-1040 BT. The method used to analyze the statistics and know the state seismisity is the ordinary least squares method and used for the mapping program Arc View GIS 3.3. The results showed that the relationship of the frequency of occurrence with earthquake magnitude scale 5 SR is very often in Bengkulu province, while a earthquake scale at 6 is rarely. Seismisity index value that occurs in Bengkulu province, to shallow earthquakes is about 0.08977 to 0.54181 and medium-sized earthquakes ranged from 0.01303 to 0.22141. Bengkulu province is a region with a high level of seismisity, where rarely for large earthquakes, but small-scale earthquakes are often. After calculation of the incidence of earthquakes in each region, the author got earthquake return period has a different other by other. in addition of years makes the high risk of earthquakes is highly and the earthquakes occur concequenced by shear or fault plate.
