Schedule for an organization meeting
of the

Pacific Northwest Region of the Advanced National Seismic System (ANSS)

June 15, 16 in Seattle


Thank you for your interest in the organization meeting of the ANSS in the Pacific Northwest. The response from the invitation letter is large. Unfortunately there is no one time that works for all respondents, but the time with the fewest conflicts is June 15 and 16. Therefore the meeting will be held on those days at a site in downtown Seattle (still firming up the exact spot). Detailed directions and an agenda will be sent to you around June 1, 2000.

In the meantime we would like to stimulate some thinking on key issues for this workshop so that you will be prepared to help with the planning process. As mentioned in the invitation the two days will have somewhat different focuses. Day one will be used to update everyone on the status and plans of the ANSS at the national level and to hear from the user or client community what they expect from the ANSS and to design a method for providing steering or oversight for network design and operation. The second day will primarily be devoted to the seismograph network operators to discuss issues of their organization, management and coordination. All invitees are welcome to attend both days; however those whose main interest is in the products and oversight need not feel obliged to attend the second day.

Additional background and other information

By way of additional background on this meeting we can recommend several other documents (some are enclosed in the hard-copy mailing of this note). A one page information summary sheet is available on the WEB at URL: http://geopubs.wr.usgs.gov/fact-sheet/fs075-00/ (in PDF format). A summary of the current status of the ANSS can be found at: http://www.anss.org A diagram of a draft orrganization structure for the ANSS can be found at: http://www.anss.org/images/ANSSdiagram.gif Information about a network already providing some of the products anticipated of the ANSS is the Southern California TriNet. Information on it can be found at: http://www.trinet.org.

Details of how the Pacific Northwest Seismograph Network (PNSN) is currently operating and some of its products can be found at: http://www.ess.washington.edu/SEIS/PNSN with a one page summary at: http://www.ess.washington.edu/SEIS/PNSN/INFO_GENERAL/INFOSHEET. The PNSN is the major seismic network currently operating in the northwest; however it is not the only one and there are many aspects of the planned ANSS which the PNSN does not address. In particular the PNSN has little experience with providing strong ground motion data and information of use to engineers. A regional plan must address this issue as well as the one of having distributed resources for both data collection and information dispersal.

Please review these materials and think about what types of services and products apply specifically to our part of the country so that the workshop can can used to best advantage for our needs.
