Fifty-three more-or-less separate networks were found, distributed throughout the United States, including Hawaii and Alaska, along with four relatively permanent networks operated in foreign countries by U.S. investigators.

"Crucial questions" posed by respondents covered such matters as rising telemetry costs, the mixing of operational and research costs, need for stable policy and funding, precariousness of the northeast United States network support, wide variability of data quality, instrumentation improvements, coordination of hardware and software development, the unique role of Alaska in U.S. seismology, future of global and national networks, an assessment of the value of current network practices, and the growing usage of seismologists as technicians.

• The question on nonpaying users brought a wide response, with almost all networks involved routinely in providing data in some form to a variety of individual, industrial, and governmental users. Exhibit B-3 illustrates the diversity of users.

"Major problems facing network operations" were perceived as follows: No. Responses Problems l8 Funding, in general, at stable and continuing level 5 Vagaries of agency policy toward regional networks 5 Rising telemetry costs 4 Funding to upgrade equipment l Generally poor data quality l How to cut operational costs

Lamont-Ooherty Geological Observatory, in the East, reports that their network operators spend approximately l0 percent of their time in providing data to engineers and private consultants who require information about hazards, plus the news media and private citizens who regularly contact them for information on earthquake hazards with the desire to be educated about earthquakes in general. Virginia Polytechnic Institute and State University lists: Virginia State Office of Emergency and Energy Services (for planning)
