Comparison of the Effect of Different Instrument Piers on the Waveform Records
Peng Wu · Journal of Seismological Research · 2011
We did an experiment to study the effect of instrument piers on the seismic waveform records by setting the same type of seismometers and data acquisition devices on the three instrument piers at Wu'an seismic station,Hebei Province during Jul.,2009—Mar.,2010.The contrast experiment shows that the waveform recordings are the best when the seismometers are set in the recess of bedrock.
