The data is originally from USGS and was made available by someone as a spreadsheet. I updated it with information from Wikipedia, especially on 2010 and 2011 earthquakes. I also added country and continent information and several Wikipedia links and images. The updated data is also available as spreadsheet on Google docs.
Thanks to Sigrid Dösseler, Del Myers, Christoph Treude and Margaret-Anne Storey for helpful design suggestions. The earthquake visualization was in part inspired by this blog post on visualizing earthquakes and these two visualizations of recent earthquakes.
