The United States frequently tested nuclear weapons in the Pacific with the equivalent power of 1.6 Hiroshima's per day. The largest test, Castle Bravo, was 1000X more powerful than the bomb dropped on Hiroshima

Castle Bravo was just one nuclear test out of the 68 that the United States conducted over a 12-year span (1946-1958) in the Republic of the Marshall Islands. Measured by their power, these nuclear tests amounted to 1.6 Hiroshimas per day over that period – a fact little known to the world community.
