PROCESS OF DETECTION OF TSUNAMIS APPLICABLE FOR ALL CAUSES OF THEIR EXCITATION Russian patent published in 2000 - IPC

FIELD: seismic seawaves warning service. SUBSTANCE: amplitude of disturbance vector of gravitational field caused by wave which is equal to , k = (k2x

+k2y)^1/2 is measured, ρ being water density, γ being gravitational constant, h being wave height, being wave vector. Direction of propagation of wave , and wave height h= or h= are defined by measured amplitudes of disturbance vector of gravitational field. In this case equality of amplitudes can be used as independent parameter in addition to spectral characteristics of measured signal which indicates that measured disturbance of gravitational field is caused exactly by tsunamis but not by seismographic factors which has another spectrum. EFFECT: enhanced authenticity of detection of tsunamis independent of type of their emergence to increase efficiency of operation of seismic seawaves warning service.
