The USGS is now testing out Twitter to collect early response information about earthquakes: “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.“ Social media can be a valuable tool in helping to assess earthquake hazards through anecdotal information from hundreds and potentially thousands of local users.
