Earthquakes that happen above latitude 45 are closer to the pole; the ones between +-45 degrees are closer to the equator.

Since the earth is a sphere, the total area of the earth's surface between +-45 degrees is about 70% of the total area (1/sqrt(2) to be precise). In other words, there is "a lot more earth near the equator than near the poles" - more than twice as much. This means that if earthquakes occurred with equal probability anywhere in the world, you would expect the answer to be a resounding "yes".

If you take into account the maps you are showing, I think that the answer is still yes - even without doing a detailed calculation.
