At a recent conference of the American Geological Society, geophysicist Roger Bilham of the University of Colorado in Boulder, presented his report and conclusions that the number of powerful earthquakes in 2018 will increase significantly.
Roger Bilham studied earthquake statistics above magnitude 7 on the Richter scale, from 1900 to the present, and found that strong earthquakes occur more often if the Earth’s rotation speed around its axis decreases slightly. This happens for some internal reasons that occur in the bowels of our planet.
In the 20th century, five such periods of deceleration were recorded and during these periods, the number of powerful earthquakes increased sharply. If at the usual time up to 15 strong tremors occurred, during the deceleration periods their number increased to 30 per year.
The next period of slowing down the Earth’s rotation speed will occur in 2018, and hence the number of powerful earthquakes will increase dramatically.
