It has been determined that in the period of solar activity increase (11-year
cycles) there increase seismic and volcanic activities in the compression zone of
Earth and at the same time there decreases the activity in the tension zones of Earth.
On the basis of the discovered stable 11-year and 22-year cyclicalities in the seismic
and volcanic activities and their high correlation with solar activity there has been
made the long-term forecast until 2018. The next maximum of seismic and volcanic
activity with very high amplitude for the compression zones of Earth is forecasted for
the period 2012-2015. --- Transactions of the International Academy of Science H & E.
