Did You Feel It

The DYFI Annual Viewer shows the highest intensity felt at each location for which we have user responses. The data is grouped into 10 km blocks, and the color of each block corresponds to the highest intensity calculated for that block (regardless of which event). By default, the data shown are from the most recent year. Other years as well as the highest intensities over the history of the DYFI system in aggregate (since 2000) can be seen by expanding the "Annual DYFI? Responses" link in the layer list. This will display all the available years for which DYFI data is available. Click on any year to display the highest intensities felt for that year.
