Novarupta plate boundary

WebThe eastern margin of the North American plate is the slow-spreading mid-Atlantic ridge, which runs north through Iceland and to the east of Greenland into the Arctic basin. Hence, Greenland, almost entirely underlain by Precambrian crust, is geologically part of North America and, more specifically, part of its Precambrian core, Laurentia. WebMegathrust earthquakes are defined as interplate earthquakes caused by one tectonic plate being forced under another in a subduction zone. During the lifetime of a subduction zone, two plates are constantly moving towards each other, and due to the great amount of friction, these plates get “stuck” in various areas 2 (fig 1).
