2004 Indian Ocean earthquake and tsunami and a network of sensors is needed to detect it. Setting up the communications infrastructure to issue timely warnings is an even bigger problem, particularly in a relatively impoverished part of the world. Tsunamis are more frequent in the Pacific Ocean than in other oceans because of earthquakes in the "Ring of Fire". Although the extreme western edge of the Ring of Fire extends into the Indian Ocean (the point where the earthquake struck), no warning system exists in that ocean. Tsunamis there are relatively rare despite earthquakes being relatively frequent in Indonesia. The last major tsunami was caused by

The Ring of Fire was named when the first significant mineral finds were made in the region, by Richard Nemis, after Johnny Cash's famous country and western ballad. Nemis, the founder and president of Noront Resources, was a lifelong fan of the singer. Prior to its discovery, Canada and the United States were compelled to rely on offshore sources for chromite, principally from South Africa.
