EARTHQUAKE PRECURSOR MEASUREMENT SYSTEM Russian patent published in 2008 - IPC G01V9/00 

FIELD: geophysics.

SUBSTANCE: said utility invention relates to geophysics and may be used in seismology during construction of geophysical exploration sites in earthquake generating regions of the planet. The substance of this invention is as follows: the system contains meters of the parameter observed, spaced at the measurement base of the site, connected to a network of time-synchronised PCs for processing of recorded information. Each meter contains a deep cased well with a sensor/transducer installed in it. The wells are drilled to the bedding rock of the geological formation. An inertial mass with seismic background transducers attached to its edges, located in mutually orthogonal planes in the x, y coordinates is lowered on the solid base into each well. The x edge plane coincides with the measurement base direction. Each sensor is connected to the input of a processing circuit consisting of an amplifier, a spectrum analyser, a detecting section, an analogue-to-digital converter, and a PC connected in series.

EFFECT: increased prediction reliability.
