After the New Madrid adjusts, the Atlantic will adjust at the same latitude, across from the continental US and from Mexico, which will surge to the west. This would seem to place the tsunami directly across from the mouth of the Mediterranean and Spain and the coast of Africa. But this is not a typical tsunami that like most has a push in a particular direction. Most tsunami results from a plate dropping or rising, and thus there is a bulk of water with more pressure than the surrounding ocean. Thense the rapid movement away from that point of pressure. If land rises the tsunami is moving away from the back of the rise. If land drops, it is moving from where water has rushed into the void, away from the lip of land that rose above the dropping plate.
For the European tsunami, there will be a large void, a spreading apart, not rising or falling land on either side of the fault line. When water rushes in, it will clash in the center of the rift, and rise up. Thus, undecided in what direction it wishes to go, it will be very subject to the existing Gulf Stream, which will propel the excess water pressure in that direction. The Gulf Stream does not go directly into the mouth of the Mediterranean, which in any case could absorb a tsunami impact and dispel it quickly. The Gulf Stream tends to curl in two directions: curling round in a circular motion back upon itself and heading north toward Britain. Where it curls upon itself, the bulk of the tsunami there will return to the rift again, and settle, not causing any perceptible high tides along the African coast or in the Caribbean.
But the thrust northward will continue and will assault the coastline of the UK directly, and secondarily the coastline of France and Norway. France can anticipate a tsunami of 100 feet, Spain perhaps 30-40 feet, the UK 200-300 feet, and Norway 50-75 feet. The full brunt of the tsunami that strikes the UK will also wash through the English Channel, entering the North Sea, and clashing with the any flow coming down from the Norwegian Sea. The lowlands in the North Sea can expect a tsunami an estimated 100 foot high. The speed and force of the tsunmai as it reaches these lowlands will be lessened, however, so blockades such as storm doors may be somewhat useful in countries such as the Netherlands. Nevertheless, much flooding will occur, forcing the residents in these countries to face what is coming for them during the pole shift.
