The state-of-the-art Streckeisen STS-5A seismometer is now installed outside of EOAS’ building

A couple of weeks ago, the Streckeisen STS-5A seismometer given to the FSU-EOAS department by Dr. Bob Hutt was set up on the South side of the new building.
This state-of-the-art apparatus constitutes an advanced instrumentation technology for global seismological research.

The seismometer was lowered into a 143′ 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.

When the data logger gets connected to the internet, the data will be collected by the US Geological Survey’s National Earthquake Information Center (NEIC) and the Incorporated Research Institutions for Seismology (IRIS).
The data will also be collected by the USGS Albuquerque Seismological Laboratory from which Dr. Hutt retired in April 2017. Seismological data are open sources, anyone will be able to access it from IRIS and use it for research and Earth’s Sciences.

Thanks to Dr. Hutt’s contribution, EOAS’ Faculty and their students as well as the whole scientists’ and researchers’ community will benefit from the seismometer’s data.

Plot showing two minutes of 3-component ground motion (vertical, north-south, and east-west) from the seismometer. The higher frequency motions seen are from traffic noise on Tennessee Street and from building motions and people walking around nearby. The lower frequency motions seen are from ocean waves coupling into the sea floor and propagating along the surface of the earth.
