All but 3 of the world's 25 largest volcanic eruptions of the last 11,700 years occurred at volcanoes in the Ring of Fire. The Ring of Fire is a direct result of plate tectonics and the movement and collisions of lithospheric plates.he Ring of Fire is a direct result of plate tectonics and the movement and collisions of lithospheric plates.
Other, much smaller earthquakes also occur away from plate boundaries such as those related to volcanic activity in Hawaii or those related to wastewater injection wells in Oklahoma. You can view a YouTube version of this animation here. Notable Features. The great majority of earthquakes occur at tectonic plate boundaries. 1  The majority of great earthquakes (magnitude 8.0 or larger) are megathrust earthquakes that occur at convergent plate boundaries, also called destructive margins or subduction zones. For an earthquake to pose a tsunami hazard it needs to vertically move the seafloor; therefore it needs to be large (typically 8.0 or larger), under or near the ocean, and shallow within the earth (less than 100 km).
