| Abstract | : | Before and after the powerful Japanese magnitude 8.9 earthquake of 11 March 2011 some gravitational effects were registered in large areas across the Eastern Hemisphere as far as 9,000 km away from the earthquake’s epicenter. The gravity anomalies were measured experimentally using ATROPATENA stations, new physical registering devices deployed in Indonesia (Yogyakarta), Pakistan (Islamabad), Azerbaijan (Baku) and Turkey (Istanbul). The stations continuously measure changes in time of the natural gravitational field in three mutually perpendicular directions. It has been established that indications of the Cavendish balance can be influenced by the dynamics of lithospheric stress fields altering the density and mass of large rock strata under the measuring stations before strong earthquakes. The authors believe that those stresses can be carried by tectonic waves. The effects registered provide a theoretical and experimental basis for initiating creation of an international network for monitoring and early warning of seismic hazards. |
