Abstract:
The results of the analysis, based on the parameters of events and some features of
seismicity that have occurred in the Lezha-Ulqini seismogenic zone during period of time
2001-2012, are presented in this paper. This seismogenic zone presents a significant seismic
hazard to those living in northwestern Albania, southern Montenegro not only due to the
pending earthquake but also due to a lots of earthquakes certain to follow the mainshock. In
total, 112 earthquakes are registered during overmentioned period in this zone, and one with
ML=5.0 (Richter) occurred on 21 August 2009. Lezha-Ulqini seismogenic zone present a
threat to nearby urban areas in Albania and the Montenegro. The goal of this study is to
determine tipology of seismicity, the source parameters of the mainshocks and their
aftershocks in order to shed light on the seismotectonics of the area on the stress field and to
evaluate the seismic hazard. The region affected by the August 2009 sequence, together with
the seismogenic region of the 15 Aprile 1979 Ulqini event (M7.0), forms a roughly NW−SEtrending
active seismotectonic zone in western Albania and continues through southern
Montenegro.
