USGS Earthquake Data Online

Permalink | Comment (0) ~ Internet

This morning, there was a small (magnitude 3.1) earthquake in the “Santa Cruz Mountains”:1 in the small town of Felton. More precisely, three miles NNE of Felton at 37.096N, 122.049W.


It’s so kewl that Google takes long, lat data
Yahoo! doesn’t… come on Yahoo!

You can read all about the quake “here”:2 on the USGS site.

It’s amazing the kind of data that you can find almost instantaneously on quakes. A few minutes after I felt this one, I popped online to see if it had been registered at the USGS. Indeed it had.


The color red represents “today”, while the size is proportional to magnitude

I picked up the screenshot of the map above at the USGS’ “Recent Earthquakes in California and Nevada”:3 homepage.

If you want to report feeling a quake, you can do so “here”:4. From these reports, the USGS site also generates “response maps” of the quakes. “Here’s”:5 one for the Felton quake.


636 responses from the blue-shaded areas.
Color represents reported intensity

And finally, the USGS generates a couple of graphs analyzing the response data. The top is _intensity_ vs. _distance from the epicenter_ and the bottom is _number of responses_ vs. _the time since the earthquake_.


“Here’s”:6 a link to the original image.

Sometimes the government works.
