Did I feel an earthquake? Can I report feeling an earthquake?
Report an earthquake experience or related observation through the Did You Feel It? citizen science webpage.
The best way to do this is to click on the earthquake that you think you felt on one of the lists on the Earthquakes webpage, and then select the "Tell Us!" link.
If you don't see the earthquake you think you felt, use the green "Report an Unknown Event" button on our Did You Feel It? page. Maps and graphs are produced from the responses in real-time.

Earthquake hazards: a national threat
Earthquakes are one of the most costly natural hazards faced by the Nation, posing a significant risk to 75 million Americans in 39 States. The risks that earthquakes pose to society, including death, injury, and economic loss, can be greatly reduced by (1) better planning, construction, and mitigation practices before earthquakes happen, and (2)...

USGS Forecast for Ground Shaking Intensity from Earthquakes in 2017
USGS map displaying intensity of potential ground shaking from natural and human-induced earthquakes. There is a small chance (one percent) that ground shaking intensity will occur at this level or higher. There is a greater chance (99 percent) that ground shaking will be lower than what is displayed in these maps.
