One enterprising VizWorld reader sent me a link to a nice Google Mashup of USGS Earthquake data, cataloging every major quake of the last century.
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. The updated data is also available as spreadsheet on Google docs.
i miss in this graph the last earthquake in Chile. febrary 27th 2010, 8.8º. We can’t forget it yet.
