The 2011 Japan tsunami was triggered by a massive earthquake and caused widespread destruction along the country's northeastern coastline, with waves traveling up to six miles inland in some areas. The disaster had a significant impact on the global economy, particularly in the automotive and technology industries. Japan has since invested heavily in building sea walls and other protective structures along its coastline, as well as launching campaigns to educate residents about tsunamis. The disaster also prompted a renewed focus on disaster preparedness and response among governments and organizations worldwide.
