표준 측정 방법에 기반한 가속도 지진 센서 특성 평가

다국어 초록 (Multilingual Abstract)

The current calibration process for seismometers is not in accordance with the international meteorological standard. The contemporary increase in seismic and volcanic activity around the Korean Peninsula has highlighted the necessity for and importance of compliance with the international meteorological system. This paper details the evaluation of a characteristic seismic accelerometer according to the international standard procedure. The dynamic and static sensitivities of the seismic accelerometer are calibrated, and the degree of uncertainty of the calibration process is also evaluated based on the standard procedure for vibration accelerometers. Results indicate that the seismic accelerometer is notably sensitive to changes to the excitation frequency and direction of vibration. Therefore, the results show that the conventional method widely used in the field of seismology, of merely noting a single nominal value when using a seismometer, is subject to clear limitations.
