Everybody knows that description of the feelings they often experience during intense lovemaking. How many of us have said that we ‘felt the earth move’, as we trembled in excitement. That statement is far more prophetic than you might ever have imagined, because somewhere on the planet, every thirty seconds of every day, an earthquake happens somewhere. Of the 1,000,000 quakes that happen every year, only 100 cause serious damage.
These movements in the Earth’s crust are caused by the continuous shifting of tectonic plates, huge land masses that are in constant motion, migrating across the face of the planet. The Pacific Plate is driving slowly under the North American Plate, right where the San Andreas fault line lies. In the Far East, much of the ground movement is caused by the so-called ‘Ring of Fire’, a huge circular area of intense volcanic activity.
