Dettifoss in Vatnajökull National Park
The waterfall Dettifoss is located in Vatnajökull National Park in Northeast Iceland, and reputed to be the most powerful waterfall in Europe. It is also the largest waterfall in Europe in terms of volume discharge, having an average water flow of 193 cubic meter per second. Its volume often increases, especially when the weather or volcanic activity prompts glacial melting on the Vatnajokull glacier icecap.
