Beschreibung / Inhaltsverzeichnis:
A Databank was created using data from 25 local catalogues and 30 special studiesof earthquakes in central, northern and northwestern Europe. Event types werediscriminated, fake events and duplets eliminated, and different magnitudes andintensities converted to Mw. The conversions require the establishment of regressionequations. The Catalogue contains tectonic events from the Databank within the area44°N-72°N, 25°W-32°E and the time period 1300-1993 which have Mw magnitudesof 3.50 and larger. The area is covered by different polygons. Within each polygononly data from one or a small number of the local catalogues, supplemented by datafrom special studies, enter the Catalogue. If there are two or more such catalogues orstudies providing a solution for an event, a priority algorithm selects one entry forthe Catalogue. Then Mw is calculated from one of the magnitude types, or frommacroseismic data, given by the selected entry according to another priority scheme.The origin time, location, Mw magnitude and reference are specified for each entryof the Catalogue. So is the epicentral intensity, I0, if provided by the original source.Following these criteria, a total of about 5,000 earthquakes constitute the Catalogue.Although originally derived for the purpose of seismic hazard calculation withinGSHAP, the Catalogue provides a data base for many types of seismicity andseismic hazard studies.
