Editing North Sea (section)

=== Tsunamis ===
Though rare, the North Sea has been the site of a number of historically documented [[tsunami]]s. The [[Storegga Slide]]s were a series of underwater landslides, in which a piece of the Norwegian continental shelf slid into the Norwegian Sea. The immense landslips occurred between 8150 BCE and 6000 BCE, and caused a tsunami up to {{convert|20|m|ft}} high that swept through the North Sea, having the greatest effect on Scotland and the [[Faroe Islands|Faeroe Islands]].<ref name="spiegel">{{cite news

The [[1580 Dover Straits earthquake|Dover Straits earthquake of 1580]] is among the first recorded earthquakes in the North Sea measuring between 5.6 and 5.9 on the Richter scale. This event caused extensive damage in [[Calais]] both through its tremors and possibly triggered a [[tsunami]], though this has never been confirmed. The theory is a vast underwater landslide in the [[English Channel]] was triggered by the earthquake, which in turn caused a tsunami.<ref name="Belgium"/> The tsunami triggered by the [[1755 Lisbon earthquake]] reached Holland, although the waves had lost their destructive power. The largest earthquake ever recorded in the United Kingdom was the [[1931 Dogger Bank earthquake]], which measured 6.1 on the [[Richter magnitude scale]] and caused a small tsunami that flooded parts of the British coast.<ref name="Belgium">{{Cite book

In 1995, the {{convert|25.6|m|ft|abbr=on}} tall [[Draupner wave]] occurred in the North Sea, becoming the first [[rogue wave]] to be observed using scientific instruments.<ref name="TheWeek2">{{cite web |date=27 September 2010 |title=The last word: Terrors of the sea |url=http://theweek.com/articles/490823/last-word-terrors-sea |access-date=15 January 2016 |website=TheWeek}}</ref>
