In the rapidly evolving political landscape surrounding nuclear testban and nonproliferation treaties, there is a window of opportunity to ensure that the international seismic system will contribute broadly to multiple issues of national concern, including earthquake monitoring and basic research on earth structure and processes, as well as treaty verification functions. Small nuclear tests, such as might be part of a clandestine weapons program, produce ground vibration levels equivalent to those of thousands of natural seismic events that occur each year.

History has repeatedly demonstrated that basic seismological research efforts are an essential part of the national strategy for long-term treaty verification. These are required both to enhance treaty monitoring capabilities and to ensure a pool of seismological expertise for future monitoring efforts.

Failure to follow through on the recommendations, especially those concerned with data accessj watt lead to duplication of effort in the seismological system and underutilization of seismic data acquired at substantial cost. The primary recommendations of this report are summarized below: Data Characteristics It is important that the data characteristics of the new TSMS stations be compatible with the broad needs of seismology in general as well as fifing treaty monitoring requirements.

Data Access Within the United States Given suitable data characteristics, the ISMS data set can contribute to diverse efforts that address earthquake monitoring and basic research on earthquakes and earth structure, as well as the nuclear test-ban monitoring effort. To enable these multiple uses of the seismic data, it is important to establish convenient pathways for data access in the United States that do not interfere with the nation's primary operations of the nuclear test-ban monitoring effort.

From page 5... ...
Costs of operating the ISMS-NDC should be provided by the nuclear monitoring community; incremental system costs for external data transmission should be provided by the earthquake monitoring agencies and by agencies supporting research on nuclear explosion and earthquake monitoring. To facilitate interagency data transmission and to deal with cost issues, the ISMS-NDC should establish a multiagency advisory committee, with representation from the nuclear monitoring, earthquake monitoring, and basic research communities, to address data distribution issues.

The incremental costs involved in establishing and maintaining this pathway should be borne by agencies supporting research on nuclear explosion and earthquake monitoring. · Seismic event data (arrival times, amplitudes, ray parameters, final event bulletins)

From page 7... ...
The development of the prototype ISMS International Data Center and other advanced computer technology capabilities and high risk/high return research topics currently sponsored by ARIA should be sustained.

National Data Center, would provide effective communication between the operational and research environments. Implementing the recommendations of this report regarding data characteristics, data distribution, and research infrastructure will ensure that the United States derives maximum benefit from its participation in the ISMS.
