Early tonight the USGS released data summarizing Americans’ responses to today’s earthquake by ZIP code. The agency uses a complicated formula that’s different from the commonly known Richter magnitude scale, but basically the data show how people experienced the event.
Here’s a quick map I made in ArcGIS of the states closest to the epicenter. Darker hot colors represent greater magnitude:
Here’s a view of DC. My ZIP code, at the top right of the DC diamond, apparently received the most dramatic responses. All I noticed at home was a toppled bobblehead doll (though that could easily be attributed to one of our cats, I suppose).
