Figure 4. First and second panels: Global spatio-temporal activities of any user in the social network.

Number of entries for inter-tweets times (first panel) and inter-tweets spaces (second panel) between consecutive tweets, before, during and after the main event on 4^th July. The dashed line indicates a power law ~ τ⁻² and is for guidance only. Third, fourth and fifth panels: Joint probability density of inter-tweets times and inter-tweets spaces between consecutive tweets before (third panel), during (fourth panel) and after (fifth panel) the main event. In both cases, only the sub-set of geo-located tweets is considered.
