I created a video to animate six months of 2010 New Zealand seismic activity data picked up by the GeoNet sensors. The animation begins in April and ends a few days after the 7.1 quake that hit Christchurch on September 4. Keep in mind three things when you view the video.
- Blue circles represent seismic activity recordings.
- Each event leaves behind a small, pale red dot to show the overall pattern.
- Most events are either small, deep or both.
Note how sparse the pattern of spots across Canterbury is until early September.

The data comes from the excellent folks at the New Zealand Geonet project. You can download the data as a spreadsheet from magma.geonet.org.nz/resources/quakesearch/.
I created the individual animation frames using Python and matplotlib. I stitched the images together with FFmpeg. I acknowledge the New Zealand GeoNet project and its sponsors EQC, GNS Science and LINZ for providing the data.
