Detected events and number of “relevant” tweets. The panels show detected events globally (a), in the United States (b), in Indonesia (c) and in Tanzania (d). Events in admin1 regions are included. This figure only shows tweets (in blue) when part of a detected event. A selection of events is labelled for reference. *The number of tweets is displayed as a 3-day average as otherwise the bars become too small to be visible in the figure.
