The possibility of using the calibrated macroseismic field parameters of the analogue region in order to increase the accuracy of the near-real time assessment of the earthquakes consequences with application of the “Extremum” System has been investigated. For the region of Albania, which is a part of the Alpine-Himalayan seismic active zone, a set of parameters is used, obtained by calibrating the macroseismic field model in another region of this zone located in the Caucasus and having similar features of tectonic development. The obtained results showed the feasibility of using an approach based on the identification of analogue regions as the first iterative step to increase the reliability of near real time loss estimates. The efficiency of a multistep, iterative approach for macroseismic field models calibration is shown, which is carried out after any damaging and disastrous earthquake. The feasibility of the database with the description of seismic events usage in the proposed approach to calibrate macroseismic fields models of “Extremum” System was confirmed.

Key words: near real time loss estimates, damaging earthquake, macroseismic field, Alpine-Himalayan seismic active belt, “Extremum” System
