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.
Although some estimates place the number of deaths from the earthquake and fires at around 700, the number is now thought to be at least 3,000. The 1906 earthquake remains one of the most significant earthquakes in U.S. history. Scientists study the quake as an example of seismic cycles in the Bay Area in which a huge quake, of magnitude 7.0 or more, is preceded by a series of smaller earthquakes.
