A 9.0 magnitude earthquake struck off the coast of Japan near the city of Sendai at 2:46pm on March 11, 2011, triggering a destructive tsunami with waves heights of 6 to 10 meters that caused severe damage. The earthquake and tsunami most affected the Tohoku region of Honshu, Japan's largest island, which includes coastal cities and towns where the highest waves and worst damage occurred. Japan has the third largest economy in the world and is a major exporter of transportation equipment, electronics, machinery and chemicals, but the earthquake and tsunami disrupted global supply chains and markets.
