I don't know how the myth got started in the media that tsunamis
are unlikely in the North Atlantic, but they only have to go back 75 years
to see how wrong they are.
In November/1929 a powerful submarine earthquake dislodged a huge slab from the Grand Banks off Newfoundland, triggering a tsunami that
killed 29 women and children in southern Newfoundland.

And that example is just for starters.

1755: A powerful earthquake and 'tsunami' killed 30,000 in the Lisbon
area of Portugal.

Morocco was hit with some very powerful earthquakes in the past 100 years, more will happen, and a tsunami is possible nearby.

Iceland is prone to some powerful volcanic and earthquake activity,
and some future date one such event may generate tsunamis from off its shores....The Mid-Atlantic Ridge is by no means a geologically quiet zone.

FINALLY! There are disturbing geological reports out of the Canary Islands about a dangerous volcano that may within the next 200 years suffer collapse and a catastrophic tsunami of unimaginable proportions may result.
I wouldn't want to live in Florida, North Carolina's coast or on Long Island
when it happens.
