Mauna Loa

Mauna Loa, located in Hawaii, is the largest active volcano is the world. Mauna Loa is a shield volcano, comparable to many of Earth’s other large volcanoes. According to Caitlin Kelly with USA Today, “Shield volcanoes are formed by many lava flows that build up and create long, gentle slopes, rather than a steep-sided mountain.” Shield volcanoes emit low viscosity lava, which means the lava flows easily. This creates an enormous landform with a wide base. Mauna Loa makes up 50% of the Big Island of Hawaii, with an area of 2,035 square miles. In Hawaiian, Mauna Loa means “Long Mountain.” Data from the Hawaiian Volcano Observatory shows that Mauna Loa rises approximately 13,680 feet above sea level, and 16,400 feet below.

This Hawaii Volcano has erupted 33 times since 1843. Its most recent eruption was in 1984. The 1984 eruption lasted from March 25 to April 15. Before the eruption, increasing seismic activity could be felt on the island. During the eruption, many lava flows were produced, but fortunately, no lava reached the city of Hilo (“1984 Eruption”). There is a high likelihood that Mauna Loa will erupt again someday, so the volcano is closely monitored.
Mauna Loa’s summit caldera, or crater, is named Moku`aweoweo and “has an area of nearly 6 square miles and a depth of 600 feet (“Mauna Loa”). Moku`aweoweo is estimated to have collapsed around 600-750 years ago.
Kelly describes the climate on the Big Island. The immense mass of Mauna Loa has an effect on the island’s climate. The volcano prevents some heavy winds from reaching the west side of the island, resulting in the west side being warmer and dryer. The eastern side receives substantial rainfall allowing vegetation and greenery to flourish. The summit of the volcano is sometimes covered in snow, due to the high altitude and cold temperatures (Information on Mauna
