Official Description

The Streckeisen STS-5A seismometer was lowered into a 143ft deep well drilled by GFA International and is capable of detecting ground motions from earthquakes as small as magnitude 5 on the other side of the earth (and much smaller earthquakes if they are closer). Earth movements are detected by the seismometer and converted to a digital signal by an external digitizer: the Quanterra Q330HR data logger.
Dr. Joe Steim, Quanterra Inc’s owner, presented the seismometer and Quanterra Q330HR data logger to Dr. Hutt as a retirement gift in April 2017.


In a borehole that is drilled to the bedrock. Southside, EOAS building, 30ft West of the PVC hydrowell head.
