what a volcano is supposed to look like"
perfect cone of Ngauruhoe is very young - only about 2500
years old, and very active - the most active in New Zealand after
White Island, with an eruption every 2-3 years until it's last
event in 1975. The crater used to steam continuously but it is
thought the vent is now blocked - preventing any further activity.
There are two craters on the top of Ngauruhoe, one inside the
other. The inside crater was formed during a larger eruption in
1942. Fresh lava flows can be seen on the slopes from eruptions
in the '40's & '50's.
