Why isn't there any tsunami's in the arctic when....?

Question

When half a mountain falls into an ocean and it makes a bunch of waves which eventually makes itself to land and causes a tsunami, why doesnt that happen in the Arctic? Because of Global Warming, the ice melts, big chunks of ice fall into the water but yet it doesnt cause a tsunami? Why does that happen?

Answer 1

Tsunamis do occur in all oceans.  When traveling in deep open water the tsunami has little or no height to speak of.  What makes the tsunami wave big is when the lower part energy wave start to drag and 'trip' on the ocean floor in shallower water.  This makes the wave stand up as the upper part of the wave overcomes and mounts the lower part of the wave.

The great tsunami of a few years ago that killed at least  1 million people was only about a foot high in free ocean passage.  But when it started to reach the up sloped ocean floors near islands and continents it rose dramatically.

The Ar tic area is relatively deep and has no slope to cause the tsunami wave to 'trip.'

Answer 2

tsunamis are usually caused when techtonic plates under pressure from colliding slip below each other causing cassms 10km deep on the ocean floor, thats a lot of energy, a glacier or half a mountain falling into the sea doesnt compare
