Prof Simon Haslett commented on The Hell of High Water: Tsunami and the Cornish Coast. The general thinking is that these types of massive submarine slides, like Storegga, are triggered shortly after deglaciation when sea-level rises to cover the continental shelf and increasing overburden water triggers a slide. Given that sea-level has been reasonably stable for the past 5-6,000 years, it is considered that most shelf-edge sediments would have slipped by now if they were unstable. However, current and future rising sea-level due to climate change and seismic activity do present a risk as a potential trigger for future events. Also, in the North Atlantic melting Greenland ice might also trigger seismic activity due to ice unloading, which has the potential to generate North Atlantic tsunami. I'd be interested to learn more about your own surveys.- 1 month ago
