Abstract:
The seismic analysis of the earthquake of 26 November 2017 with magnitude Mp4.1, realized in the area of Klissura, is presented. The spectral characteristics of the earthquake are explored using the Brune model. Applying this model, features associated with the earthquake source, such as the stress drop (∆σ), the source radius and the seismic moment (Mw) magnitude, are determined. A detailed study of the macro-seismic field of impacts is presented for the earthquake. The Micro Seismic Drilling Method for the observed event is also applied.
