All things KIWI or a trip to the Auckland Museum

The Auckland  museum is a majestic Georgian style building located in a beautiful park called the Domain.
After a long first day, my plans were to spend time learning about New Zealand's natural history.  The museum is magnificent!  The first exhibit that I entered was a wildlife photography contest that highlighted winners from all age groups and from all over the world.  This was the award winning photograph and every picture told a story, captured more than just images, and had everyone admiring in awe.       Next exhibit was on the evolution of wildlife in NZ.  Seeing the birds "stuffed" is not quite my preferred manner, but it did give me a perspective of size and class of the different species.  On to the Native Maori exhibition and to view some of the wooden carvings that they are knows for creating.  I just did a quick overview as I have more opportunities to have the Maori cultural experiences on my journey.  The exhibit that captured my interest was the "Volcano" exhibit.  The history of the volcanic formation of NZ was presented in time lapsed video.  To say that the formation of NZ has been violent is an understatement.  And, as the Tongarriro eruption yesterday proves, it is not over yet.  New Zealand volcanoes are subduction in nature as opposed to "hot spot" areas like Hawaii.  The difference is that hot spot volcano are spawned by hot lava building up pressure and exploding, sending the hot lave flowing down the mountainside, while the hot gases escape fairly easily so that of the two types, these can be less damaging.  The subduction volcanoes heat sea water to a temperature which heats and melts the rock, builds pressure and then when it erupts, it does so with an incredible violence due to the steam, the sticky viscosity of the lava, and the gases are trapped in the lava.  Ash spewing from the subduction is around 77% silicone which is what glass is made of.  This means that the ash is full of tiny shards of glass floating in the air and setting on the ground.   Breathing problems can ensue as well as damage to anything it covers.  If cars are covered and you "scrape" the ash off, you will scratch the paint.

  1. Oh my...
    I think there is a name for that particular kind of explosive eruption...Vesuvian, maybe?
    I must look that up!

  3. Well, I was thinking of a land eruption, unfortunately. A Vulcanian eruption, to be precise. They usually explode from stratovolcanoes, and are the lesser of two eruption. Plinian is the other eruption, and that's more like a Mount St. Helens explosion, complete with pyroclastic flows and lahar.
    Scary!

    By the way, and great interactive site for creating volcanos is http://kids.discovery.com/games/build-play/volcano-explorer

    Lots of fun!

    1. I saw pictures of the lahar that happened in the 80's...so devastating! They have all three types of volcanos here, and interestingly, there is a group of three volcanos in National Park...one of each kind.

    2. Oh! Well, that's rather interesting. One of each kind?

  5. Mrs. Moore!
    Such great vocabulary you use to describe the two types of volcanoes! I'm impressed; I love viscosity, shard,spew. :)
    How in the world do they get the ash off their cars without scratching them?!

  7. Too bad it was just a photography exhibit!! Amazingly awesome pictures I am sure, but it would have been so cool to actually see all those animals!

    1. You and I could have stayed for hours in the exhibit. They had a competition for kids ages 11-14 and a kid from North Dakota had a winningly amazing photo. So much talent at such a young age.

  8. They didn't have a model volcano did they? How disappointing considering the history of New zealand...

    1. Mary, they had movies of several eruptions and you could sit in a house with a simulated eruption happening...shaking side to side and up and down...quite the jolt(s)! They had several models of the different types of volcanoes and where they are located inNZ. Learned lots!

    1. You would have loved it! But, we have lots of wonderful museums in Richmond, and DC is very close with the Smithsonian. We have so many great museums to visit that are close :-)
