<P> About 90 % of the world 's earthquakes and 81 % of the world 's largest earthquakes occur along the Ring of Fire . All but three 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 : the movement and collisions of lithospheric plates , especially subduction in the northern portion . The southern portion is more complex , with a number of smaller tectonic plates in collision with the Pacific plate from the Mariana Islands , the Philippines , Bougainville , Tonga , and New Zealand . </P>
