another Google way of visualizing earthquake distributions

Monitoring earthquake occurrences and studying their patterns is a persistent pastime for residents of Southern California.  I really like this Google tool (new to me) called ninepointfive.org.   The default “particle” view is a little weird, but when I switched it to the more familiar “rings” format, it all became much clearer to me.  It takes a little time to load the long lists from previous years, but all seems to work well when I’m patient for a few seconds (an eternity in today’s cyberspace).
