This article is about Mount Tongariro in New Zealand which is on North Island. This volcano erupted on November 21st for five minutes and through clouds of ash 2.5 miles up into the atmosphere. The volcano is 6,490 feet tall and had previously erupted in August, which was the first eruption since 1987. There is also predictions that a similar eruptions will take place in the next few weeks although the activity on the mountain has stopped for the moment. Much like Mount Eyjafjallajökull, the Icelandic volcano that erupted in 2010, air travel has become difficult. Obviously not on the same scale as the eruption of Eyjafjallajökull in 2010, which crippled air travel throughout all of Europe. But air travel on New Zealand's North Island has been stopped. The reason for the cancellation of flights is that in volcanic dust there is microscopic pieces of glass and when they enter a turbine engine they can become hot enough to melt. When they melt they can create significant damage within the engine and sometimes cause it to stall. On top of that the visibility of pilots can be reduced to zero when they fly through the ash and it can also damage the windows of the plane. Much like sandstorms can damage the windshield of a car. One interesting part of this volcano is that it neighbors the mountain depicted as Mount Doom in the Lord of the Rings Trilogy. I think that this is not a global environmental issue because the volcano that erupted is not large enough to affect a significant part of the planet like Mount Eyjafjallajökull did in 2010. However if a full scale eruption was to happen the impact on New Zealand would be terrible. Especially with the affect it would have on the beautiful landscape from the North Island that is featured in the Lord of the Rings Trilogy.
