Captions: (top right) Steam and other gases boil from the northeast slopes of Mauna Loa on March 25, 1984, signaling the beginning of an eruption lasting 21 days. The photo was taken near this point.; (center) Mauna Loa is the largest of the five major volcanoes on the island of Hawai'i, accounting for more than one-half the islands's land mass. Most of the volcano lies hidden below the ocean's surface. By volume, Mauna Loa is 100 times larger than Mt. Rainier, an older volcanic peak of about the same elevation in Washington state.; (center right) A fiery fountain on the flank's of Mauna Loa feeds a lava flow (lower left) during the 1984 eruption.

Inscription.  In front of you looms the world's largest active volcano

The summit of Mauna Loa stands 20 miles ahead of you, reaching an elevation of 13,677 feet above sea level and more that 31,000 feet above the ocean floor. With a volume of 10,000 cubic miles, Mauna Loa is the largest mountain on Earth.
The volcano's great mass is being built by successive flows of hot molten rock, or lava. The thickness of an individual lava flow averages 12 feet. Mauna Loa is classified as a shield volcano, a volcano with gently-sloping sides resembling a warriors's shield overturned. Kilauea, the volcano you are now standing on, is also a shield volcano.
It has taken hundreds of centuries and countless eruptions for Mauna Loa to reach its present size. During the last 100 years , the volcano has erupted more than 18 times, The next eruption could occur at any time.
