Hawaii Volcanoes National Park came into being as a component of Hawaii National Park in 1916, but it it wasn't until September 22, 1961, that it became a stand-alone unit. The fireworks for its 47th "stand-alone birthday" are being provided by Kilauea, one of the world’s most active volcanoes. An eruption that began March 19 has yielded half a dozen explosive eruptions, a roiling lake of lava, and a mile-high ash plume.
