Recent devastating earthquakes in Haiti, Chile and China, as well as magnitude 7 plus earthquakes in Indonesia and California, might give the impression that earthquake activity is increasing. In fact, a quick look at earthquake statistics over the last twenty years shows that this is not the case. On average there are about fifteen earthquakes every year with a magnitude of 7 or greater. As with any quasi-random phenomena, the number of earthquakes each year varies slightly from this average, but in general, there are no dramatic variations. So far this year, there have been six magnitude 7+ earthquakes, in keeping with the annual rate.
