"The longterm development and support of permanent seis mograph networks must be a responsibility of government because of the magnitude, expense, and international nature of global earthquake monitoring. But in the United States, a stable federal program for such support does not exist. The U.S. program for global seismograph networks is frag mented and suffers from the lack of a longterm funding plan, and these problems are even more serious in view of current research needs and recent technological advances in instrumentation and data processing that must be in corporated into the Worldwide Standardized Seismograph Network (WWSSN).
