On Aug. 9, 1945, the U.S. dropped a second atomic bomb on Nagasaki, about 260 miles southwest of Hiroshima. That bomb, known as Fat Man, was more powerful than Little Boy, but Nagasaki’s hilly terrain lessened the damage. An estimated 70,000 people were killed.

When the first atomic bomb detonated 80 years ago in Hiroshima, thousands of the dead and dying were brought to the small, rural island of Ninoshima.
