Mauna Loa is an active volcano in the Hawaiian Islands of the United States.

Name

“Mauna Loa” is Hawaiian for “long mountain”.

Size

The volcano is at least 18,000 cubic miles (75,000 km³) in volume and over 4 kilometers above sea level. Measured from its base on the ocean floor, it reaches above 8 kilometers, making it the tallest mountain on Earth, but not the highest. That distinction is reserved for Mount Everest.

Measured from sea level Mauna Loa is 4,169 meters high. It is also one of the largest volcanoes measuring 60 miles long and 30 miles wide.

The world's biggest volcano is named Mauna Loa in Hawaii. Mauna Loa is part of the five volcanoes on Hawaii's 'Big Island'. The most recent time this volcano erupted was in 1984. It erupted 33 times in the last 170 years. Like all the other Hawaiian volcanoes, Mauna Loa was created by the movement of the Pacific tectonic plate which moved over the Hawaii hotspot in the Earth's mantle. It is a shield volcano. The largest recent eruption from Mauna Loa left a lava trail 51 kilometres (32 miles) long.
