ANSS - Advanced National Seismic System

Mission

Regional seismic monitoring in the IMW Region continues to rely on a geographic patchwork of seismic networks, involving both stably-funded and unstably-funded operations. Well-established networks cover most of Utah, Nevada, and Montana. Throughout the IMW Region�and especially in Idaho, Wyoming, New Mexico, Colorado, and Arizona�the challenges are to achieve adequate geographic coverage of seismically hazardous areas, especially in gaps between existing networks and in areas that have been historically neglected; stable network operations in areas where seismic hazard and/or risk warrants continuous seismic monitoring; and coordinated data exchange, uniform earthquake reporting and response, and compilation of homogenous earthquake catalogs for more systematically defined regions of responsibility.
