There are currently three active volcanoes in Hawaii. On Hawaii Island you'll find Maunaloa and Kilauea in Hawaii Volcanoes National Park. Maunaloa last erupted in 1984 and Kilauea has been continuously erupting since 1983. Loihi is located underwater off the southern coast of Hawaii's Big Island. Erupting since 1996, this emerging seamount may break the surface in about 250,000 years, adding a ninth island to the Hawaiian chain.
