Characterization of rock vibrations at the Homestake mine - The laboratory

By: Jan Harms, Angelo Sajeva, Riccardo Desalvo and Vuk Mandic

The instruments and the data acquisition are controlled remotely from our lab which is inside the Ross dry. Also, the data is regularly transmitted to our lab where we can start to analyze it. In the near future, we will have access to this system from any place in the world, so that we and our colleagues can work with the data, where ever we are and whenever needed. In the end, all data – each station produces about 2 GByte each day – will be copied to storage and analysis facilities at the California Institute of Technology. The clocks of all stations inside the Homestake mine will be synchronized to the microsecond level building a sort of synthetic antenna for rock vibrations.
