Where is the largest active volcano in the world?

Rising gradually to more than 4 km above sea level, Hawaii’s Mauna Loa is the largest volcano on our planet. Its submarine flanks descend to the sea floor an additional 5 km (3 mi), and the sea floor in turn is depressed by Mauna Loa's great mass another 8 km (5 mi). This makes the volcano's summit about 17 km (10.5 mi) above its base!
