TOKYO, April 7 (UPI) -- Niijima island is relatively new, born just last year, but it has already become an geological aggressor.
Last November, the volcano first broke through the ocean's surface, becoming Japan's latest piece of territory in the "Ring of Fire" -- a string of heightened seismic and volcanic activity in the Pacific that stretches from the coast of Chile north to Alaska and Siberia and then circles back down past Japan and the Philippines toward New Zealand.
