“Is the northern part of Iceland still there?”<br>Well yes, because even if the rock did disappear, it would no longer be the northern part of Iceland, and some other place will be the next northern part, which will then be the most northern part of Iceland.<br><br>Thank you for coming to my TED talk.,(reply>), @Cerberous+1 you are thinking way too hard, there are more, um, <i>diplomatic</i> ways if you want to get rid of Iceland :^)<br><br>kidd ofc xdd,(reply>), 👏👏👏,(reply>), @Cerberous+1 If you set up a Kickstarter for the project, I'd chip in.<br>Just out of morbid curiosity.,(reply>), @NerdOracle okay so we will need some serious equipment, some of which might not yet really be withing human technological development.  We will need to drill about 20 boreholes each about 4 miles down around the faults in the island.  Then we will need thermonuclear devices not yet build each on the order of  750+ mega tones.  So each of these 20+ devices will each need to be over 15x the power of the largest nuke ever built in history.   And even then you have to hope you placed them correctly and were not sinking the whole island.  This would all be to try and sink about a 10th or less of it.  To sink the entire island you would need to somehow deliver a device on the order of 20 gigatones deep into the magma chamber of the islands largest volcano like at the part where the chamber meets the mantel and we need to try and Essentially cause a high enough pressure the fracture the internal structure of the island.  This would possibly collapse the central volcano causing massive earthquakes and landslides and it the whole island doesn't go a new lake after a hundred years or so,(reply>), @Cerberous+1 sounds fascinating. where do we start?
