REGIONALITY OF LONG-PERIOD GROUND MOTION BASED ON THE ANALYSIS OF JMA STRONG MOTION RECORDS
|
抄録（英）：
Use of the records by the strong motion seismograph operated by Japan Meteorological Agency is pertinent to evaluate the characteristics of long-period ground motion. Digitizing seismograms was semi-automatically performed by the system composed of a personal computer and an image scanner. Fifty-eight records observed at Tokyo since 1950 were digitized, and real ground motions were estimated by removal of the instrumental response. The acceleration spectrum was predicted for the earthquake with the maximum expected magnitude and the average epicentral distance in a seismo-tectonic region, multiplying the theoretical spectrum by the amplification factor. The predicted spectra showed that the earthquake in the Izu region has the most harmful influence on Tokyo.
