The method is based on recalculation of the seismic moment into magnitude, whereas the seismic moment is obtained from spectral analysis. The method has been introduced at Polish seismic stations in the late 1990s but as of yet had not been described in full because magnitude discrepancies have been found between the results of the individual stations. The authors have performed statistics of these differences, provide their explanation and calculate station corrections for each station and each event source region. The limitations of the method are also discussed. The method is found to be a good and reliable method of local magnitude determination provided the limitations are observed and station correction applied. date: 2006-01 date_type: published publication: Acta Geophysica volume: 54 number: 1 publisher: Versita, Warsaw and Springer-Verlag Berlin Heidelberg id_number: doi:10.2478/s11600-006-0003-1 refereed: TRUE issn: 1895-6572 official_url: http://dx.doi.org/10.2478/s11600-006-0003-1 access_IS-EPOS: limited owner: Publisher citation: Wiejacz, Pawel and Wiszniowski, Jan (2006) Moment magnitude determination of local seismic events recorded at selected Polish seismic stations.
