|Chapter 3 - Earthquake Catalog|
The catalog of past earthquakes that have occurred in a region is an important source of information for the quantification of future seismic hazards. This is particularly true in stable continental regions such as the CEUS where the causative mechanisms and structures for the occurrence of damaging earthquakes are generally poorly understood, and the rates of crustal deformation are low such that surface and near-surface indications of the buildup and release of crustal stresses are difficult to identify. Because the earthquake catalog will be used to characterize the occurrence of future earthquakes in the CEUS, developing an updated earthquake catalog for the study region was an important focus of the CEUS-SSC Project. The specific goals for earthquake catalog development are described in the following sections.
