Some years ago after a big one in Japan the likelihood of one onto the NE coast was talked about.

It would be very very unlikely to occur as it’s not a very volcanic area, however there is a big question that one could occur because on a landslide on the Norwegian Coast.

If I remember correctly there is a huge cliff which they think is unstable and if a large amount goes it will send a huge wave across the North Sea. I cannot remember the height quoted but enough to devastate our east coast.

Some time after that we were diving off the Farnes and some large waves came from a NE direction. When I say large waves but more a swell but came out of an almost flat calm sea. We were in transit at the time, not actually diving. So no problem.

We thought that a large tanker or similar had gone south and it was its bow wave.

On checking after we returned home we found that there had been a big storm in the North Atlantic and the waves that we had were due to reflective wave action from Norway.

A bit of useless information until it happens.
