This BTN is about the earthquake that struck New Zealand in 2011, the effects and why it happened.
In 2011, Christchurch, New Zealand, was struck by a terrible earthquake. It killed more than 100 people and injured many more. It was so powerful that the earthquake tore down buildings and reduced everything to rubble. The magnitude of the quake was measured up to 6.3, a dangerous and damaging rate. Unfortunately, Christchurch was still recovering from a previous earthquake which had happened in the last 6 months and was measured to have a magnitude of 7.1. What has me interested is that the most recent earthquake (with a lower magnitude), caused more damage than the one before. This is because the earthquake with a magnitude of 7.1 was far deeper in the earth than the one scored with 6.3, meaning it wasn’t as close to the surface as the other. The most recent earthquake was only 5 km below ground which was why it caused so much damage.
Surely by now you must be thinking, why does New Zealand get so many earthquakes? To answer that we must take a look at the earth’s crust. See, the earth is made up of tectonic plates that are constantly moving, only by the tiniest amount. When two plates are edging towards each other, eventually they will collide or rub against each other and with that sudden movement, an earthquake occurs. Now, sadly, New Zealand is situated right on top of both the Pacific Plate and the Australian Plate which means they would experience more earthquakes then many other countries.
Touching on that, something that I now wonder is are there many other countries that are in the same unfortunate position as New Zealand? If so, are they more vulnerable or safe?
