  • Large amounts of seismic data are currently being collected and generated at a rate of approximately 3.3 Gbytes/year.
  • Several organizations (e.g., IRIS, USGS) provide a means of easily gathering open source data.
  • To utilize these data effectively for regional seismic research, a mechanism must be in place that allows easy access and usage for a researcher and efficiently stores and integrates large amounts of information and data.
  • LANL has developed a seismic research database that meets these requirements and provides a foundation for regional seismic research in Asia.
  • The seismic research database has been used for developing monitoring technologies, including discrimination techniques, travel-time correction information, magnitude calibration.
  • The seismic research database has also been used for other applications, including earthquake source studies and aftershock relocations.
