At one of the tiltmeter stations operated by us, an unusually large tilt of the ground was observed during 3 months preceding the occurrence of the strong earthquake of March 7, 1952, of which the epicentre happened to be not very far from the station.
After careful investigations of the reliability of the observations, it has been concluded that the ground tilt was really in an intimate connection with the earthquake occurrence. It is emphatically stated that the observations of the ground tilt are one of the promising methods useful for predicting the occurrences of destructive earthquakes.
