Puerto Rico Seismic Network
This is a U.S. Geological Survey project to collect information about ground shaking following significant earthquakes. You can help us by filling out a questionnaire for each earthquake you feel. A Community Internet Intensity Map will be made and updated every few minutes following a major earthquake. At first only a few ZIP codes will have intensities assigned, but over time others will be assigned as data comes in. Check back often and watch the maps change!

Didn't feel an earthquake but want to see how it works? Contribute to our test dataset.
