Analysis of downhole seismometer monitoring capability at Suifenhe Reference Station
摘要
Abstract
Suifenhe Reference Station is a newly built reference station in Heilongjiang Province earthquake intensity quick reporting and early warning project,which is equipped with a GL-CS60B underground seismometer for seismic observation.In order to verify the observation performance of the seismometer,a GL-CS60 seismometer at the surface is used as a reference to conduct azimuth inspection and calibration calculation and compare and analyze the background noise level of the two seismometers.The results show that the parameters of the underground seismometer are up to standard,and the azimuth is 164.349°.The underground seismometer has strong anti-interference ability,especially for the suppression of human interference in the 1-20 Hz band,and the background noise level of the station reaches levelⅠ,and the observation data quality is better.关键词
