Animated visualization of 4300 earthquakes and aftershocks.
http://maptd.com/visualizing-christchurchs-earthquakes
The time lapse runs From September 4, 2010 - the date of the the 7.1 magnitude Darfield quake - to the 6.3 magnitude February 21, 2011 Christchurch earthquake.
Larger circles represent stronger earthquakes. The small, static dots are epicentres.
After the Darfield earthquake the aftershock sequence follows the typical pattern of gradually tailing off. With events diminshing in magnitude and frequency.
Occasionally, towards the end of a pattern like this, there's another major event and it starts over again. Sadly this what happened in Christchurch.
