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).
Yes. Earthquakes of SOME intensity happen SOMEWHERE every day. There were 2 strong earthquakes today, one in Italy, one in Tonga. The running tally for 26 October 2016 from earthquaketrack.com:99 earthquakes today681 earthquakes in the past 7 days3,156 earthquakes in the past month41,088 earthquakes in the past year
There were 3 big ones (September 4th 2010, February 22 2011 and 2 on 13 June 2011. Although there have been dozens of other large ones (between magnitude 5-6) there have been well over 9,000 earthquakes/aftershocks to date. These still occur everyday and haven't ceased yet.
Yes. Earthquakes can be caused by 2 plates that slip past each other. This is called a transform fault.
About 2 or 3
You are thinking of Monday 13th June. There were 2 big earthquakes that afternoon. 1 person was killed in the 2nd earthquake that day (the 6.3 magnitude). 1 1/2 hours earlier there was a 5.7 magnitude.
Magnitude 2 and smaller earthquakes occur several hundred times a day world wide.

There have been over 9,000 earthquakes and aftershocks in Christchurch since the very first one on September 4th 2010. However the main 3 days these occured were: Saturday 4 September 2010 at 4:35 am. Magnitude 7.1. Tuesday 22 February 2011 at 12:55 pm. Magnitude 6.3. Monday 13 June 2011. 2 big earthquakes - 1:00pm magnitude 5.6 followed by a magnitude 6.3 at 2:20pm.

It's 156km to get to Timaru from Christchurch It's a 2 hour journey non-stop
There were 3 main earthquakes in Christchurch. FIRST: 4th September 2010 4:35 am 7.1 SECOND: 22nd February 2011 12:51 pm 6.3 185 dead 6000 injured THIRD: 13th June 2013 around 1sh 6.4
