Should we experience an earthquake of any magnitude the United States Geological Survey (USGS) has a website where they would appreciate having people report whether or not they felt the quake. The name of the webpage is Did You Feel It? 

Did you Feel It? is a citizen science project that would appreciate reports from any interested individual. The project collects information from people who felt an earthquake and creates maps that show what people experienced and the extent of damage. And they are also interested in reports of who did not feel an earthquake that was in their area. 

Take a look at the webpage on Did You Feel It to learn more about the project and so you can participate if you wish. The FAQ section of the page tells how the information is used and why it is useful. https://earthquake.usgs.gov/data/dyfi/index.php
