The name of the world's largest active volcano is Mauna Loa, located on the Big Island of Hawaii. Mauna Loa is not only vast in size but also one of the most active volcanoes globally, with its last eruption occurring in November 2022. Towering over 13,000 feet (4,000 meters) above sea level, Mauna Loa covers an area of approximately 2,035 square miles (5,271 square kilometers). Its gentle sloping shape and frequent eruptions make it a subject of study for volcanologists. The volcano is part of the Hawaii Volcanoes National Park, contributing to the island’s unique geological landscape and ecosystems.
