Today 17th February, I just experienced my 3rd UK earthquake.
The house shook like a good one I have to say.
Can't find anything on UK seismic sites.......can anyone help please as friends felt it about 10 miles away.
If you are near the ocean, check if waters retreated. ASAP.
Usually, it takes an earthquake with a Richter magnitude exceeding 7.5 to produce a destructive tsunami. Most tsunamis are generated by shallow, great earthquakes at subductions zones. More than 80% of the world's tsunamis occur in the Pacific along its Ring of Fire subduction zones.

It was a 4.7, that's nothing. I live in So Cali, and it would take at least a 7 to issue a tsunami warning.
That's because we don't live on a fault line , although not rare 4.7 is quite strong for our little island.
