In an approach to event mapping, one or more computer processors extract, from one or more social networks, data, uploaded by one or more users, corresponding to an event, where the event is nature related. The one or more computer processors extract metadata associated with the data extracted from the one or more social networks. The one or more computer processors determine, based, at least in part, on the data extracted from the one or more social networks and on the extracted metadata associated with the data extracted from the one or more social networks, a current state of the event, where the current state of the event includes at least a condition of the event relative to at least a corresponding condition of a pre-defined optimal state of the event.
