The Aran Islands just off the coast of Ireland left geologists puzzled for a while now.
On top of this cliff huge boulders are found. Up to now the only explanation for waves energetic enough to transport these rocks would be a tsunami. Unfortunately, at least for the explanation, no tsunami happened there since 1755.
Now oceanography has a possible explanation for this phenomenon. Waves deflected off the steep coast can contribute to other incoming waves, accelerating these waves upwards. It just takes a decent storm to account for these boulders and the special physics of an ocean close to this cliff of the Aran Islands.
