  • Mauna Loa is the largest volcano on Earth in terms of volume and area covered and one of 5 volcanoes that form the island of Hawaii.
  • It is an active shield volcano, with a volume estimated at approximately 18,000 cubic miles, although its peak is about 120 feet lower than that of its neighbor, Mauna Kea.
  • The Hawaiian name "Mauna Loa" means "Long Mountain".
  • Lava eruptions from Mauna Loa are silica-poor, thus very fluid, and as a result tend to be non-explosive.
  • A trail leads to the summit crater with 2 hiker huts along the way.
