Abstract

A homogeneous earthquake database is required to research earthquake occurrence patterns throughout time and space, as well as for a variety of technical applications such as seismic hazard assessment, peak ground acceleration computation, and long-term seismic strain rate estimation. Naturally, its seismic network and earthquake database have evolved in tandem with advances in seismology research. Magnitude is one of the most essential factors in determining the size of an earthquake, notably in seismic hazard assessment research. A rigorous and critical examination of these studies was created to compare various interpretations of existing earthquake data in terms of seismic characteristics (date, location, and size) and to determine the most trustworthy interpretation for each tremor. In terms of moment magnitude, the earthquake catalog is homogenized. The catalog compilation technique, the elimination of redundant events, the consolidation of magnitude scales, and the declustering process are used to remove dependent events, and its completeness analysis is well explained. Several magnitude-conversion method relationships, corresponding to known locals and regionals, have been constructed to offer uniform estimates of the moment magnitude for the whole collection.
