Is there any reason for "bigger" events to happen less frequently?

A lot of scientific fields, such as hydraulics, sismology, risk analysis, rely on statistical data that show how the bigger the event is (in the mentioned subjects: precipitation, earthquake, generic hazardous event), the less frequently it happens. Is there any physical reason for this particular behavior?

For any thing to happen there are a lot of variables that come into play.

For example, lets take a forest fire. we know that some of the variables are

1. Energy source (spark)

2. Combustible substance (dry wood)

3. Oxygen

4. Wind to carry the fire

etc.

Now if all the above are available in abundance then we will have a big fire.

But if lets say there is absolutely no wind, and there is less dry wood then the fire will be contained.

Now apply this analogy to all big events. If all variables that contribute to the event are available in abundance or are maximized then we have a big event. As explained by someone else above, energy is also one more of the variables that need to be built up to a flash point.

In reality, thanks to mother nature the combination of variables needed (or to be maximized) to that lead to any really big event is quite rare.

hence relax and enjoy your world.

Bigger things cause more disruption, so if big things were happening all the time, where would the we be?
There is more energy required for these events to happen. It takes longer to build up that kind of energy.
for every action there is an equal and opposite reaction. Bigger reactions are caused by bigger actions which take more time. Also I believe that God gives praying people time to be ready.
