Continuing this thought process we can also find an explanation why features in this tectonic-north-south part of the world are oriented in this way. Many north-south striking islands have north-south striking back-arc-basins that separate them from their main land masses. And peninsulas are sometimes the arms of failed rifts or the tapering of back-arc-basins. Outside of this prevalent orientation we see features like Nowaja Semlja with very different orientations.

But be cautious with this theory. Assigning each feature on Earth to a north-south and east-west orientation gives you a 50 % chance that a randomly aligned feature will confirm your theory. Even four directions still give you 25 % chance. So the more directions you consider the harder it is to prove the theory. I am not aware of anybody doing a global peninsula inventory, so it would be interesting to see this.
