One statement you could write is that "Earthquakes of higher magnitudes are much rarer than those of lower magnitudes". The magnitude of earthquakes is a logarithmic scale, so a magnitude of 8 is TEN TIMES more powerful than a magnitude 7. This is why earthquakes of higher magnitudes are so much rarer than those of lower magnitudes.
This is not a record of a Magnitude 8 or Greater Earthquake during the year

The answer depends on the magnitude of the earthquake. Over the last 20 years there have been approx 4 million earthquakes annually which is equivalent to an average of 8 every minute. Earthquakes of magnitude 7 or greater occur, on average, 0.00003 times a minute.
Earthquake strength is measured using a magnitude scale. For small to moderate strength Earthquakes (< magnitude 7) the Richter scale is used. For Earthquakes between 7 and 8 the body and surface magnitude scales are used and for earthquakes larger than 8, the moment magnitude scale is used.
