Whenever I hear of a major earthquake, I always wonder when our turn will come. I've been asking myself that question way too frequently recently. My family and I live in the San Francisco Bay Area, prime earthquake country (or so I thought until I looked at Japan...). I started playing with NOAA's earthquake data after the New Zealand earthquake. After the recent Japan quake, I thought I'd publish a few graphics. 

Disclaimer: I'm no geologist, statistician, or expert on earthquakes. I don't even play one on TV. I don't think anyone can predict earthquakes with any certainty (though there is some interesting research) and I certainly won't try.

The Ring of Fire is the name given to the chain of mountains, volcanoes, and faults that ring the Pacific Ocean. Of the world's 16 largest earthquakes since 1900, 15 occurred in the Ring of Fire.

Here's an interesting graphic showing the earthquakes above 6.0 magnitude that have hit the Ring of Fire region since 1900. Earthquakes of magnitudes between 6 and 7 are in green, between 7 and 8 in blue, and 8 or higher in red.

Notice anything? Well, as a Californian, the first thing that struck me was: "we're getting off lightly!".

This movie gives you a different way to see the earthquakes. Same legend as before: magnitude 6+ green, 7+ blue, 8+ red. The video isn't the most exciting one you'll ever see. It helps to pick a point of interest on the map and imagine some elevator music in the background :-)

Let's dig deeper...
