Data from www.ngdc.noaa.gov (as of 04Mar2010)
http://www.ngdc.noaa.gov/nndc/struts/form?t=101650&s=1&d=1

I copy-n-pasted the data into an Excel spreadsheet, 
and then imported them into SAS using SAS/Access to PC File Formats.

I use empty (just outline) annotated function='pie' to represent the
earthquakes - the size & color both represent the intensity of the quake.

I also do a needle/bar chart of the data.
Seems to indicate a huge increase in the number of significant quakes
since 2002.  (And when I plot these on a map, they're mostly in China).
Has their dam caused earthquakes?  Or have they added better equipment
to monitor for quakes?
