U.S. Geological Survey Open-File Report 80–302
IntroductionThe purpose of this report is to assemble information on the growth and recording of the Hawaiian Volcano Observatory’s seismic network. It is meant as a guide for those using the seismic records to determine the availability, format, and characteristics of records on a station-by-station basis. This report is intended to be kept up to date with new entries made when stations, their recording, or their characteristics change. The emphasis is on the most recent information (1967–1 October 1979), but effort has been made to include some network characteristics back to 1950. This report also includes information on the growth of the network as recording capacity increased. Response curves and calibration factors are given in an attempt to allow users of the data to relate measured amplitudes to ground displacement, at least for data after 1974. Also included is a brief description of scale factors presently in use in setting up network electronics which relates Develocorder to magnetic tape amplitudes. Detailed descriptions of seismic instrumentation, particularly the variety of types in use before 1970, can be found in several original sources. The information presented here is drawn from these original sources, as well as log books and notebooks maintained by the technical staff. |
