SEISMOMETER-SETTING APPARATUS AND METHOD FOR SETTING SEISMOMETER-SETTING APPARATUS

PROBLEM TO BE SOLVED: To solve the problem where conventionally an observation technique for vertical seismic motions has not yet been developed apart from a large amount of economic investment and a large amount of time is required for completing new seismometer setting wells in the new seismometer setting well alone. SOLUTION: A seismometer-setting apparatus comprising a first drill rod and a lower seismometer storage cylindrical part, and a seismometer-setting apparatus comprising a second drill rod, a first casing break part, a vertical seismic motion-transmitting arm base, a concrete press-in part, and an upper seismometer part enable a plurality of seismometers to be set to different depth positions of a stratum in a seismological observation well.
