Landslides are a serious geologic hazard common to almost every state in the United States. "Did You See It?" is a crowd sourcing initiative launched by the U.S. Geological Survey's Landslide Hazards Program to collect data about the occurrence of landslides within the U.S.

The information will not only help scientists better understand the causes of landslides, possibly leading to improved disaster mitigation strategies, but also serve as public resource to educate citizens about potential risks in their communities.

USGS scientists may use some of the information that citizen scientists enter in qualitative descriptions of damage in USGS publications. Citizen scientists would be identified as “an observer” and their locations would be given in general terms. Parts of some first-person accounts may be reproduced as quotations in USGS publications.
