A fast moving mass radiates part of its energy through gravitational waves. It is possible to consider hurricanes and earthquakes as terrestrial sources of quadrupole gravitational waves. These phenomena have the necessary parameters for the generation of gravitational waves: large quadrupole moments m/r2 and also energies and masses moving with large velocities. Estimates indicate a possibility of observing gravitons from the source of a strong earthquake. Local changes in the earth's gravistatic field and the generation of a gravidynamic field during earthquakes will cause variations in the trajectories of the moon and artificial satellites. A mathematical theory of trajectories, containing gravitons, will enable us to fix the graviton according to data from trajectory measurements.
