WebThere are about 1,350 potentially active volcanoes worldwide, aside from the continuous belts of volcanoes on the ocean floor at spreading centers like the Mid-Atlantic Ridge. About 500 of those 1,350 volcanoes have erupted in historical time. Many of those are located along the Pacific Rim in what is known as the "Ring of Fire."

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). WebMagma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed. Two plates …
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.
