Post-earthquake imagery of Christchurch, New Zealand is now available through Google Earth and via a special Picasa web album link; both options allow you to see images from before and after the quake.

With this map, Earth Observatory connects the two major earthquakes to hit Christchurch, New Zealand:
This map shows the earthquakes that occurred near Christchurch since September 3, 2010. On that day a magnitude 7.1 quake struck to the west of Christchurch. Black circles represent earthquakes from September 3, 2010, until February 21, 2011. Red circles show the locations of the magnitude 6.3 quake and aftershocks on February 22 and the morning of February 23. Larger circles represent stronger earthquakes. Yellow shows urban areas, including Christchurch.
The Christchurch Quake Map is an animated map that “aims to present a time-lapse visualisation of the earthquake and its aftershocks, primarily to help those outside the affected area understand what those of us in Canterbury are experiencing. It plots earthquake data from GeoNet on a map using the Google Maps API, with the size of the circle denoting the magnitude (the higher the magnitude, the larger the circle) and the colour showing the focal depth (see the legend below the map).” Via Collins Maps Blog.
