HELIOGEOTECTONICS

The possible trigger mechanisms by solargeomagnetic origin for excitation of part of terrestrial tektonics events (earthquackes and volcanic erruptions) are subject of the present study. Evidences, that some of the most significant tektonic events during last decades are close correlated with solar eruptive processes and corresponding geomagnetic storms, are given. The most powerful eruption in 20th century of the Pinatubo volcano in 1991 as well as the catastrophic Japan’s earthquacke in 2011, March 11 are considrered as examples. Adetailed analysis over the Pinatubo eruption, where the solargeomagnetic trigger effect even in the separated phases of volcanic eruption is clear visible, has been provided. The possible physical mechanisms for generation of solar-geomagnetic trigger forcing over Earth tektonics are discussed too.
