Abstract:The idea of Beaumont and Berger Beaumont and Berger, 1974] about the possibility of earthquake prediction by means of continuous monitoring of temporal changes in tidal response was able to achieve effective application only in recent years after the appearance of GPS-data on the Earth’s surface displacement field in the seismic regions and the Global Seismographic Network (GSN), containing tidal, tiltmetric, and gravimetric data of measurements in the epicentral areas. The results of statistical analysis of the tidal response of the medium in the vicinity of the epicenters of the earthquakes in Peru (2001), in Sumatra (2004), and in Chile (2010) are presented.
