Want this question answered?
because they were strong
The reason that there have been so many aftershocks after the 2010 Christchurch earthquake is because bigger earthquakes have not only stronger aftershocks, but more of them. Aftershocks happen because when an earthquake occurs, the earth's plates hardly ever settle into a stable position straight away. So, the newly moved rock has to be settle.
Do you know why the Christchurch earthquake such a bad one.Because, so many people have died in this earthquake. Have you ever noticed it. That there's a hundreds of people died and especially our beloved buildings that have been destroyed and we can't go inside because of the damage and it my fall, and we get on trap. That's so sad.So for today and forever I say that the Christchurch earthquake is such a bad one. I hope all of you too.THANK YOU!!!!By: Micah Catampo
Because it just was and earthquakes can happen anywhere so there Because that's where it happened. If it had hapened in Wellington it would have been called the "Wellington earthquake".
cause it just did.....

A previously unknown fault activated. Alarmingly so, for ground acceleration exceeded 2g in some sites! Have a crack at Christchurch Earthquake in wikipedia, which has a good summary of events.
There are so many big buildings have been destroyed and people have been killed.

The earthquake in Christchurch, NZ on the 22nd of February, 2011 was located just 4 or 5km underground. To put this in perspective, the quake in September, located near Christchurch was twice the depth, 10km below ground. So although the quake may have been 6.3 on the Richter Scale, it was a lot shallower than the one in September (7.3 on the Richter Scale), did a lot more damage and took many, many more lives. Hope this helps.
It was midday, so many people were out and about in the business center of Christchurch. The earthquake epicenter was very close to the surface, only five kilometers under Christchurch, so buildings were more seriously shaken. Most people were killed in a couple of big buildings, the CTV Building and the Pyne Gould Corporation Building where people were working through lunch.
they havnt or christchurch woulkd be fine by nowresidents have hjad to movesome residents have left christchurchand the quakes are till happening so no one can respond!
The 2010 Christchurch earthquake was of magnitude 7.1. The 2011 Christchurch earthquake was of magnitude 6.3. The 2011 Japan earthquake was of magnitude 9.0. The formula for comparing the energy released by two earthquakes using the moment magnitude scale (which is what I assume those numbers are in, since it's the most common scale for large earthquakes) is D=103*(m1 - m2)/2 So compared to the more recent Christchurch earthquake, we get that the Japan earthquake was about 103*(9.0-6.3)/2 = 103*2.7/2 = 104.05 which we can tell even without actually doing the calculations is a bit over 10,000 times more powerful in terms of total energy released. (this does not, however, mean 10,000 times more damage).
The plates moved so this can occur the earthquake.
