A computer implemented method of producing macro-view conclusion data related to a seismic event. The method includes receiving at a processing center a set of data related to a parameter of a seismic event. The parameter is measured using a vibration sensor of a hard disk drive of a computer at a known, fixed location, wherein the vibration sensor produces the set of data. The method further includes processing the set of data at the processing center to produce the macro-view conclusion data. The macro-view conclusion data is then stored in a storage device.
