There are a lot of earthquake happened in New Zealand. It’s like Japan! Earthquake will happen by mantle’s moving. Mantle is always moving, and striking other mantles. Then both mantles will sink and after that, mantle can’t stand that condition so suddenly they try to return. It’s earthquake’s constitution.

New Zealand has more than 150 of active fault. There are southernmost capital of the world Wellington, but there are surrounded by fault .For example, Wellington fault line.
So, it’s located just on area of earthquake happened frequency. Moreover, there are a lot of New Zealand’s center agencies and high buildings. So if earthquake happened in this area, there are suffered big damages.

In New Zealand, there are an earthquake of magnitude 6.0 is happened once a year. Magnitude 7.0 is happened once ten years. Magnitude 8.0 is happened once hundred years. On the other hand in Japan, magnitude 7.0 to 7.9 happened 45 times after 1900. Moreover, there are more than magnitude 8.0 happened 9 times. So that’s because it’s clear that Japan is more dangerous from earthquake disaster than New Zealand.
