On 21 September 2004 the northeastern area of Poland has experienced two unusual earthquakes of magnitudes 5.0 and 5.3. The earthquakes have originated in the nearby Kaliningrad Region, Russia, across the state border. Although the damages were minor and no casualties have been reported in Poland, the appearance of such earthquakes in an area otherwise considered non-seismic and totally safe has caused much concern among of relief services and general population. The earthquakes will naturally cause reassessment of the seismic hazard for this area and will be subject to scientific analysis. This paper summarizes those investigations of the events that result from everyday seismological observatory routine, providing information on location and magnitude of the events. The source mechanism is also being discussed. The results are an evidence that the Kaliningrad Region is a seismically active area, even though the earthquakes happen relatively seldom and do not reach devastating size.
