Chrome WebGL app showing many geo-locations on a globe with corresponding magnitudes for each point.

There are three data feeds provided in the source file. These have been transcribed into these google maps:

• 1990 shows apparently random points distributed throughout the world. They don't appear to correspond to cities or known landmarks, but should be investigated in more detail.
• 1995 shows a cluster of points around Geneva, Switzerland. See Geneva for possible meaning.
• 2000 also shows a cluster of points around Geneva, Switzerland. See Geneva for possible meaning.
