<span>The famous Ring of Fire, that consists of basically the entire Pacific ocean.....going along California, up over Alaska and Russia, and then back down, along Japan. More of a horseshoe than a ring, really.......but that's nitpicking. 80-90% of the earth's earthquakes and volcanic activity take place along this ring......hence the name.</span>
Explanation: When two plate boundaries collide, it causes earthquakes. The deepest and most powerful earthquakes occur at plate collision (or subduction) zones at convergent plate boundaries.
