5 volcanoes make up the island of Hawaii in the U.S. state of Hawaii. It is one of the world's most famous volcanoes. This volcano was more active in ancient times and in the late 1890s and early 1900s, as the last recorded eruption was back in 1984. The volcano erupted in 1942, during World War II. The volcano has recently been showing signs of stirring, though, so we shall see if it rises again.
