The largest volcano in the world, Hawaii's Mauna Loa, has been erupting for 48 hours. The USGS announced the eruption at 11:30 p.m. HST on November 27 and lava is now flowing towards the northeast side of the island.

The United States has more volcanoes than any other country in the world, although only 42 of them have been active in the last 70 years. Of these active volcanoes, six are located in Hawaii.
