What is the world's largest active volcano?

The world's largest active volcano is Mauna Loa, located on the Big Island of Hawaii. Mauna Loa is a shield volcano and is considered to be one of the Earth's most active volcanoes. It has erupted 33 times since its first well-documented eruption in 1843.

Mauna Loa is one of five volcanoes that make up the island of Hawaii, and it rises 13,678 feet (4,169 meters) above sea level. However, if measured from its base on the seafloor, Mauna Loa is over 30,000 feet (9,144 meters) tall, making it the tallest mountain in the world.

Mauna Loa's most recent eruption occurred in 1984, and scientists closely monitor the volcano for any signs of increased activity. While the volcano's eruptions can be dangerous to nearby communities, they also provide a unique opportunity to study the processes of volcanic activity and the effects of eruptions on the surrounding environment.
