The Christchurch in New Zealand, had an earthquake of a 4.8 magnitude which happened on March 6, 2011 3:43am. This was an aftershock of the last months earthquake, February 22, 2011 which was 6.3.
The Christchurch earthquake was a magnitude of 6.3

RECENT AND HUGE On the 4th of September 2010 there was an earthquake magnitude 7.1 in Christchurch and then on 22nd of Febuary there was a 6.3 earthquake inb Christchurch
It was a magnitude 7.1, although seismologists have recently disclosed that the energy produced was very violent, and equal to an earthquake of a magnitude 8.

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).
It's very possible that Christchurch could have another earthquake. However, the possibility is low, as Christchurch had no major earthquake before the earthquake in 2010.
