Seismicity in Major Seismotectonic Provinces of Iran

Seismicity parameters,i.e.,seismic activity rate,X,the so-called Gutenberg-Richter b value(orβ),and maximum possible magnitude,Mmax,for major seismotectonic provinces of Iran are estimated through the application of Kijko and SellevolPs uncertainty models.The uncertainty models facilitated the estimation of seismic activity parameters from incomplete and uncertain data files in the catalog of earthquakes in major seismotectonic provinces of Iran.Zagros has the highest seismic activity rate,and is characterized by the occurrence of mainly small-and mid-sized earthquakes.Kopeh Dagh has the lowest activity rate but is characterized by a greater occurrence of major earthquakes.However,the Makran and Alborz-Azarbayejan seismotectonic provinces are most likely the regions which are capable of generating great earthquakes.
