Stop me !
Thanks, Tom. It's a bit messy with all the years included. To answer the question "are we having more earthquakes this year?" the best graph would have the area between the min and max shaded; and with the average line and the line for 2010 inside that envelope. If I wanted to spend the time on it, that is.
Also, the scale tends to washout what everyone is really interested in, and that's the big temblors. We are above average for the 7.0 to 7.9 range; which is difficult to see from the graph. It is not the max, though, which was 18.
We've four more months in 2010, so we'll have to wait for the final tally.
Here are the averages, etc.
