   The weak seismo-tectonic activity is known from the northeastern part of the Bohemian Massif. A great number of weak tectonic events from the northeastern part of the Bohemian Massif, which were detected by stations operated by IPE, was originated in the area northwards of Šternberk in the western part of the Nízký Jeseník region. This article is focused mostly in the most active epicentral area northwards of Šternberk which is situated near the Rýžovište. 14 from the 62 located events were located into the area near Rýžovište during the period 1996-2001. Recently active tectonic structures were originated already during Variscan or Cadomian orogeny, during the Cenozoic were reactivated and strongly affected the tectonic fabric of the northeastern part of the Bohemian Massif. Above all NW-SE trending "sudetic" faults played dominant role during the young tectonics. The epicentral area near Rýžovište " is situated in the SE continuation of the significant NW-SE Klepáčov fault.
   But on the map of the orientations of rivers and creeks, on the elevation map and on the map of Bouger anomaly, differently orientated lines are more distinct. The NNW-SSE structure of valley of the upper part of Moravice river and the line of Trusovice creek and the Lomnice creek are very significant for study of the recent tectonic activity in the epicentral area near Rýžovište. These tectonic lines cross each other directly in the studied epicentral area. The discussed NNW-SSE and NNE-SSW tectonic structures accompany significant NW-SE faults and their activity is probably connected with the activity of the NW-SE fault system in the northeastern part of the Bohemian Massif
