According to The Denver Channel.com Japan sits right in the middle of The Ring of Fire...no, not Johnny Cash's Ring of Fire, but a geological one; which in my mind makes it a damned dangerous place to be right now. Here is an excerpt from the best written article I could find on this darn tsunami that everyone is so rightly worried about:
Japan lies on the "Ring of Fire" - an arc of earthquake and volcanic zones stretching around the Pacific where about 90 percent of the world's quakes occur, including the one that triggered the Dec. 26, 2004, Indian Ocean tsunami that killed an estimated 230,000 people in 12 nations. A magnitude-8.8 temblor that shook central Chile last February also generated a tsunami and killed 524 people.
