Seismic hazard assessment for Central, North and Northwest Europe:: GSHAP Region 3

The activities of the Regional Centre 3 of the Global Seismic Hazard Assessment Program (GSHAP) covering Europe north of 46 degrees N and west of 32 degrees E are summarized starting with the establishment of the GSHAP Centre at the GFZ Potsdam in 1993 and leading finally in the calculation and creation of the GSHAP seismic hazard map in terms of horizontal Peak Ground Acceleration (PGA). Moreover, the activities of separate working groups which contribute with their results for certain parts of the study area to the final product of the Regional Centre are described. Details are given on the development of the homogeneous seismicity working file, the delineation of seismic source zones, the data preprocessing as well as on the chosen PGA-attenuation relations.
