Earthquake catalogs contain data about time of occurrence, hypocentral coordinates, earthquake magnitude, and other earthquake information. The data is derived from the observations of different seismic wave types, generally from heterogeneous networks of seismometers in space–time domain. Earthquake catalogs provide useful inputs for studies dealing with seismicity, seismotectonics, internal structure of the earth, and seismic hazard assessment. A homogeneous earthquake catalog is of critical importance for the study of earthquake occurrence patterns in space and time, seismic hazard estimates, land-use planning, seismic microzonation, and other seismological applications. These studies require well-defined and consistently determined earthquake magnitudes. Historical seismic records usually do not fulfill this criterion. |
