Mauna Loa is one of the most massive volcanoes on Earth, located on the Big Island of Hawaii. It is a shield volcano, characterized by its broad, gently sloping sides formed by the eruption of low-viscosity lava. Mauna Loa covers an area of about 2,035 square miles and rises approximately 13,681 feet above sea level, making it a prominent feature of the Hawaiian landscape. The volcano is known for its frequent eruptions, with the last one occurring in November 2022. Mauna Loa is closely monitored by the United States Geological Survey due to its potential impact on nearby communities and the environment. Its eruptions contribute to the unique geological features and ecosystems of the Hawaiian Islands.
