Recording strong motion studies
Instruments now permit strong‐motion signals to be recorded over broader band widths, with wider dynamic range and signal resolution and with better data accessibility via computer. These advantages are utilized by the General Earthquake Observation System (GEOS) developed by the United States Geological Survey, by which a microcomputer‐controlled system provides improved strong‐motion data sets, as described here by a member of the development team. The paper was originally given at a joint meeting of the US/Japan Panel on Wind and Seismic Effects.
