I’ve never thought about a tsunami when visiting the beach in my life. Are they much more common in the Pacific? We go to the Gulf and Atlantic and it’s never something I think about. We usually go in June/July, so we don’t worry much about hurricanes either.
There is no Atlantic ring of fire, is there. What little places like Iceland show is nothing compared to what pacific has to offer in much larger area.
While the Atlantic doesn't really have many faults that will generate earthquakes causing tsunamis there is always a risk of landslides creating large tsunamis up to what we'd consider mega-tsunamis. This said this is something that may have thousands of years between incidents.
