All Over the Map: Investigating the Did You Feel It? Citizen Science System
The Did You Feel It? (DYFI) system allows Internet users to report earthquake data when they feel an earthquake. The data submitted are put into computer programs that create "Did You Feel It?" Maps. More than 4 million entries have been submitted from 1999 to 2017. The scientists wanted to know how the DYFI system changed from 1999 to 2013. Additionally, the scientists wanted to measure the accuracy and timeliness of the DYFI system data.

Note To Educators
The Forest Service's Mission
The Forest Service’s mission is to sustain the health, diversity, and productivity of the Nation’s forests and grasslands to meet the needs of present and future generations. For more than 100 years, our motto has been “caring for the land and serving people.” The Forest Service, an agency of the U.S. Department of Agriculture (USDA), recognizes its responsibility to be engaged in efforts to connect youth to nature and to promote the development of science-based conservation education programs and materials nationwide.
What Is the Natural Inquirer?
Natural Inquirer is a science education resource journal to be used by students in grade 6 and up. Natural Inquirer contains articles describing environmental and natural resource research conducted by Forest Service scientists and their cooperators. These scientific journal articles have been reformatted to meet the needs of middle school students. The articles are easy to understand, are aesthetically pleasing to the eye, contain glossaries, and include hands-on activities. The goal of Natural Inquirer is to stimulate critical reading and thinking about scientific inquiry and investigation while teaching about ecology, the natural environment, and natural resources.

Citizen Science Connections
The Did You Feel It? (DYFI) system was created to gather information about earthquakes from the people who experience the earthquakes. Using the Internet, scientists can get information quickly about what citizens experience and the effects of earthquakes. Scientists who study earthquakes combine the citizen-based science data from DYFI with state-of-the-art data collection technology.
Did You Feel It? lets citizen scientists:
• Search and view data on earthquakes around the world;
• Report earthquake events in their location;
• Learn about the science of earthquakes.
Did You Feel It? is a project of the U.S. Geological Survey. The DYFI system has collected nearly 3 million data points from citizen scientists since 1997.
