The world's largest active volcano is Mauna Loa, located on the Big Island of Hawaii. Covering an area of about 2,035 square miles (5,271 square kilometers), it rises approximately 13,678 feet (4,169 meters) above sea level, although its base extends much deeper into the ocean floor. Mauna Loa is classified as a shield volcano due to its broad, gently sloping sides created by the eruption of low-viscosity lava. It is monitored closely for volcanic activity and has erupted multiple times, the most recent significant eruption occurring in November 2022. This volcano is not only a natural wonder but also an important part of Hawaii's culture and environment.
