Patent ID: 6985817

Claim:
A system for the prediction of earthquakes which comprises: at least three peripheral detection stations distributed in predetermined positions over a territory, each station being capable of detecting the low frequency electromagnetic waves which are released as a result of mechanical stress of the underground rock layers, a central processing station which receives signals relating to said electromagnetic waves from each of said peripheral detection stations and processes said detections in order to obtain an indication of the epicentre and on the entity of the earthquake, characterized in that each of said peripheral stations comprises at least one ring aerial for each of the directions defined by a series of three Cartesian axes suitable for detecting said electromagnetic waves, at least one of the ring aerials is a wide band aerial and is equipped with a receiver suitable for detecting a band in a preferred receiving frequency of said electromagnetic waves substantially free of disturbance frequencies, and tuning the reception of all the ring aerials on said disturbance-free band, a cancellation circuit of impulsive atmospheric disturbances received on a different frequency band, which allows a signal to be obtained at the outlet, which only comprises premonitory signals freed of all disturbances.
