The histograms show some interesting facts:
- Quake frequency decreases exponentially with magnitude, or vice versa: small earthquakes are MUCH more frequent than larger ones. The apparent decrease of very small earthquakes towards lower magnitude is because tiny quakes (below magnitudes 3 or so) are only being registered in a few places of the world, but in reality occur in their thousands every day.
- Even though smaller quakes are much more frequent, they release much less energy combined than a single large one.
The reason is that earthquake energy increases by a factor of 30 for each magnitude step: for example, a magnitude 6 earthquake contains as much energy as 30 magnitude 5 quakes!
