Introduction to Ngauruhoe: Ngauruhoe is a cone-shaped volcano with a steep slope and a crater with a diameter of 400 meters at the top. It is a very typical cone-shaped volcano. Ngauruhoe volcano is billowing with smoke all year round. It has been active since the 1830s. The eruptions of Ngauruhoe volcano are colorful. Sometimes the erupted lava flows down the slopes, changing the shape of the volcano. The eruption also causes the shape of the crater itself to constantly change, regenerating secondary volcanic cones in the main crater. This is also the filming location for the movie "Lord of the Rings" and "Mountain Doom".
