Did You Feel It?
If you felt an earthquake, we would like to hear from you. Please fill out the US Geological Survey's Community Internet Intensity Survey (we only need your ZIP code). Data you submit will be merged with felt reports of other people to produce a map of ground shaking effects. Even if you did NOT feel the earthquake, let us know that. The data you submit will be sent to UUSS electronically.
