Pagination or Media Count:
Five high-gain, broad-band, long period seismograph stations are being installed around the world. The instruments will probably have gains on the order of 100,000 or more at periods of 40 to 50 sec. This high sensitivity, some 50 to 100 times greater than previously attainable at these periods, should lead to a similar increase in the data now available in the long-period band. The purpose of this report is to describe the instruments, present a preliminary parts list, and present technical drawings of most of the newly designed components. The five sites are also briefly described. The report is written at a time when construction has begun at four sites.
