Tweets have been used in disaster research. Geotagged tweets allow one to identify the geographical pattern of the event-related tweets. Then sentiment analysis of those tweets may reflect Twitter users’ concerns and emotions associated with an event. This research aims to compare the geographic patterns of the two terrorist attacks in London, UK in 2017. We extracted the geotagged tweets and investigated their sentiment in spatial relationship to the incidents. The results suggest that geotagged tweets clustered in both space and time. Tweets closer to the incident locations had a stronger emotion than those further away.
