Abstract

Value of slope of a recurrence curve γ which shows earthquakes number distribution on their energy and which is widely used for seismic process characteristics was studied (with the help of a magnitude scale). Earthquakes referred to Mingyachevir reservoir zone for the time period 1935-2002 and 2003-2014 have been chosen by the data of RCSS ANAS catalogues. Time variations of slope of an earthquake recurrence curve value were investigated for Mingyachevir reservoir zone. Investigations on the basis of fractal statistics of the earthquakes in the given zone were carried out and the map of seismic activity for a period of past 10 years was made.
