  The excitement and convergence of tweets on specific topics are well studied.
However, by utilizing the position information of Tweet, it is also possible to
analyze the position-sensitive tweet. In this research, we focus on bomb
terrorist attacks and propose a method for separately analyzing the number of
tweets at the place where the incident occurred, nearby, and far. We made
measurements of position-sensitive tweets and suggested a theory to explain it.
This theory is an extension of the mathematical model of the hit phenomenon.
