Two Australian and Pacific
Because New Zealand is sitting on two tectonic plates which cause volcanos when the move.
54,506 yeah there are a lot!!
one plate, the pacific plate
There are seven tectonic plates depicted in this setting.
New Zealand is centred on the edge of two tectonic plates. Australia isn't anywhere near an edge, so it is safe.
Tectonic plates, 3 plates
there are 7 huge plates but dozens of smaller plates
New Zealand, like a few spots round the world, straddles two Tectonic Plates, the Pacific and the Australian. The movement between these two plates causes several things definitely New Zealand. The Volcanoes, the Alpine Fault, the Southern Alps.The Alpine Fault commences well south of NZ, continues through the country to emerge as the Hikurangi Trench, then the Tonga Trench and so on.
it happens when the tectonic plates under the earth collide or push into each other to cause disruption so an earthquake would happen in a place were there is the edge of 2 tectonic plates underneath.
