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
Ring of Fire (Northern Ontario) the report it commissioned by the engineering firm Tetra Tech regarding the viability of building a railroad, instead of a road, to access chromite in the Ring of Fire. KWG's 100 percent owned subsidiary, Canada Chrome Corporation, "staked a 330-kilometre-long string of mining claims" creating a transportation corridor linking Cliffs/KWG's Big Daddy chromite deposit to CN Rail (CN) near Nakina, Ontario. According to KWG, their subsidiary, Canada Chrome Corporation "conducted a $15 million surveying and soil testing program for the engineering and construction of a railroad to the Ring of Fire from Exton, Ontario."
