Graph showing the annual average number of worldwide earthquakes of each magnitude calculated over the last 20 years. This shows how earthquake numbers decrease as magnitude increases. For example: there are roughly ten times as many earthquakes of magnitude 6 than magnitude 7.CLICK TO ENLARGE.n average there are about 15 earthquakes every year with a magnitude of 7 or greater. As with any almost random phenomena, the number of earthquakes each year varies slightly from this average, but in general, there are no dramatic variations.
Most quakes are unnoticeable by people on the surfacein fact, thousands of quakes occur every day around the globe, most of them too weak to be felt. Every year, scientific instruments detect about 500,000 quakes worldwide. People feel only a small fraction of those. On average, a magnitude 8 quake happens every year somewhere on Earth. But severe earthquakes that cause widespread destruction happen on average once every five years. These great quakes can destroy cities, burst dams, trigger volcanic eruptions, and set off landslides and giant sea waves.
