Wont the Hawaiian chain Caldera run into the Yellowstone Caldera before this one forms fully ?
I would thing NZ was formed by a super type volcanic events over millennium but my NZ geology is a bit lacking. So Im not surprised they have a Caldera under there.
Actually, jokes aside, there's a lot's about the geology of NZ that we dont know, such as the fact that NZ used to be a large continent.
Most of the north Island is formed by Volcanic activity. Earthquakes are a daily occurance here, there's a lot of active volcanic and geothermal areas too.
I've been watching the volcano's and Earthquakes a lot since the Christchuirch quake, There's deinately been an uptick in activity down here. Especially since August last year when Tongariro woke up.
