It certainly seems like there have been more large earthquakes in the last few months than usual. What's the standard deviation for seismic joules per month or year? I posted about this on my outdoors blog here. What I'd really like to see is an animated GIF of the USGS California earthquake map. Like this:
[Added later: Turns out they do have such a page, which can be found here. It rocks]
This one is just a 2-shot animation over 6 days. Granted 2 data points isn't great, but I'm not going to take a shot every day and make a new GIF. It looks like the quakes around Mexicali and El Centro are a) getting smaller/less numerous and b) migrating northwest, both of which match what has been happening.
So what about it, USGS? Can't you automatically make a 1-month loop animation like Unisys does with weather satellites? This might provide researchers with valuable insights. I shot an email to the webmaster at the USGS site. [And they responded, and they are doing it. Thanks guys!]
