This report demonstrates some of the work that could be done with this type of information. It suggests that public agencies work closely with social media companies to install plans to incorporate these systems into the disaster-recovery process. Social media sites operate as critical emergency communication venues during crises, telling us where people are located during a disaster, where they are moving and in some cases where they are checking in as “safe.” This report looks at how social media, in particular, Twitter, has been used to evaluate the spatial and temporal aspects of disaster and emergency situations, including terrorist attacks, earthquakes and floods.Social media systems and crowdsourced data sites were incredibly active during Hurricane Harvey. Residents, first responders and officials all turned to these systems to impart information and make calls for assistance. These systems will likely continue to hold a central informational and communication role in future disasters. Analyzing the trends and information that come from these sources in real-time could aid the recovery process and help public agencies, first responders and researchers more quickly assess damages during and immediately after a disaster. This report demonstrates some of the work that could be done with this type of information. It suggests that public agencies work closely with social media companies and the operators of crowdsourced sites to install plans to incorporate these systems into the disaster recovery process.engCopyright ©2018 by Rice University Kinder Institute for Urban Research.
