As many earthquakes as I have experienced in various parts of California, including Loma Prieta and its multitude of aftershockes, it is always a shock when I feel one here in south central Kansas. I reported what I felt to USGS. A few minutes later, USGS posted about the earthquake, as below, with nearly 800 reports having been received concerning this latest earthquake.
I can't seem to get the lower map to display the appropriate heading. The map header should read "Geocoded Map". It shows the positions of the reports received. Note the large number of reports from Wichita (and Derby).
On its website, USGS explains the process they use in evaluating each earthquake. The explanation starts with this introduction:
This web site is intended to tap the abundant information available about earthquakes from the people who actually experience them. By taking advantage of the vast numbers of Internet users, we can get a more complete description of what people experienced, the effects of the earthquake, and the extent of damage, than traditional ways of gathering felt information. And best of all, with your help we can do so almost instantly.
By contributing your experience of the earthquake, either immediately afterward, or whenever it is possible for you to do so, you will have made a contribution to the scientific body of information about this earthquake. You will also ensure that your area has been represented in the compilation of the shaking map. This is a two-way street. Not only will you add valuable information on the extent of ground shaking and damage, but in the process we hope you will learn more about how other communities fared and gain a greater understanding of the effects of earthquakes.
