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.
Earthquake size is determined not only by amount of displacement but also area of the ruptured fault plane. Hence the larger the rupture area, the larger is the earthquake. A magnitude 7 earthquake ruptures a fault area of about 1000 km2 or about 50 km long and 20 km wide. Also depth is an important factor influencing earthquake severity. We know that earthquakes can originate at various depths within the Earthâs solid core.
