Development of a reliable rapid earthquake response system is a critical issue for the Advanced National Seismic System (ANSS). In order to accomplish this, new goals have been specified by the National Earthquake Hazard Reduction Program (NEHRP)/USGS:
1) Continued seismic monitoring for improved delineation of seismogenic faults and evaluation of hazards associated with earthquakes;
2) Improved real-time data exchange between regional networks and the USNSN and expanded earthquake reporting capabilities; and
3) To promote effective dissemination of earthquake data and processed information derived from regional networks.
To achieve these new goals, LCSN acquires seismic waveform data in near-real-time, processes the digital signals in automated fashion for determining the location and magnitude of the detected events, and issues rapid earthquake alerts. Event parameters are promptly contributed to the ANSS composite earthquake catalog via QDDS (Quick Data Distribution System) and are available through “Recent Earthquakes” provided to the public, with URL:
ShakeMap represents a significant step forward in the development of real-time seismic information relevant to post-earthquake emergency management. For regional seismic monitoring networks in the eastern US, rapid generation of the ShakeMaps pose challenging tasks, because it requires timely collection of high-quality ground motion data, and comprehensive knowledge on ground motion attenuation, regional geology and shallow site conditions.
This project addresses NEHRP Program Element I - National and Regional Earthquake Hazards Assessments, since we propose to characterize active faults and define the depth of the seismogenic layer in the northeastern US, thereby providing basic data to evaluate seismic potential of the region. We also provide focal depth and other parameters which must be used to evaluate the results produced by commonly used algorithms such as HAZUS for assessing earthquake hazards in the region. This project also addresses the program Element III - Research on Earthquake Occurrence, Physics & Effects, since we determine accurate earthquake locations, and maps of the earthquake ground motion.
