Sup guys! This will be my last update because New Zealand is my last stop! So sad :( I had an amazing week and hopefully I will be able to come back to these wonderful places! Well, anyways, I am in New Zealand right now and am making reservations at a restaurant at the Bolton Hotel. I am so excited to go swimming here because it is soooo hot! I think that the amazing race contestants will love it here because it was pretty darn cold in the Himalayas. And P.S., the accents here are so awesome, I hope I can learn it sometime!
So, what the amazing race contestants will learn, and what I have also learned, is that New Zealand lies on a transform boundary. In a transform boundary, two plates slide past each each other. There aren't spectacular physical features in these areas like there are in other types of tectonic plate areas. These places are usually marked with valleys where the rock has been ground up. In New Zeland, the Pacific plate and Australian plate are sliding along each other and causing the Alpine fault. The Alpine Fault runs along almost the entire length of New Zealand's southern islands and earthquakes along this fault have helped to form the Souther Alps.

Alpine Fault, New Zeland

Transform boundaries are common areas for earthquakes. In new Zealand, the Alpine fault has ruptured four times in the past 900 years and each time causing an earthquake of about 8 magnitude. The most recent major earthquake was in 1100 and there is a 30% chance that it will rupture again in the next 50 years, which would cause major destruction and have a giant impact on very many people. Volcanoes are not as common in transform boundaries because the plates are just sliding past each other. However, in New Zealand, the volcanic frequency is pretty high because other parts of New Zealand have plate boundaries other than transform. Eruptions mostly occur in the north island and the last major eruption was in 1996 on Mount Ruapahu. When you go to New Zealand, make sure you watch out for earthquakes and volcanoes because they can go off at any moment!
