Here’s a fine example of an innovative government social media resource and some innovative crowd-sourcing of user comments. The USGS Twitter account @USGSted is an interesting find where you can follow shakers reported by the public and access related info from the USGS. About the service… In this exploratory effort, the USGS is developing a system that gathers real-time, earthquake-related messages from the social networking site Twitter and applies place, time, and quantity data to provide geo-located earthquake detection within 60 seconds of an event’s origin time. This approach also provides a central directory of short first-impression narratives and, potentially, photos from people at the hazard’s location. See also more HERE
