Where is the largest active volcano in the world?

The largest active volcano in the world is Mauna Loa, located on the Big Island of Hawaii. Mauna Loa covers an area of about 5,271 square kilometres (2,035 square miles) and stands at 4,169 metres (13,681 feet) above sea level. However, when measured from its base on the ocean floor, Mauna Loa is over 9,144 metres (30,000 feet) tall, making it the largest volcano on Earth. It has erupted 33 times since its first well-documented eruption in 1843, and it is closely monitored by scientists due to its size and potential for future eruptions.
