Where is the largest waterfall in the world by depth and water volume?

Question

Which is the world's largest single-drop waterfall by volume and among the tallest and most powerful waterfalls in the world?

Answer 1

The Denmark Strait
At the bottom of the Denmark Strait between Iceland and Greenland are a series of cataracts that begin 610 m (2,000 ft) under the Strait’s surface and fall to a depth of over 3,000 m (10,000 ft) at the southern tip of Greenland, creating a downward flow estimated at well over 3.5 million cubic m (123 million cubic ft) per second. The Strait cataract is more than 3 times the height of Angel Falls in Venezuela, considered the tallest waterfall (on land), and its flow is equivalent to a minimum of about 140 times the flow of the Livingstone Falls (and close to 2,000 Niagara Falls at peak flow).
