Thousands of people congregate at the San Fermín festival in Pamplona. By analysing camera images from the Plaza Consistorial during the chupinazo in four editions, a team has modelled what the movement of this human tide looks like. The physical theory of dense crowds can be applied in other circumstances, say the authors, who include scientists from the University of Navarra. In their paper published in Nature, they offer a strategy to anticipate these movements in real time and help prevent events such as avalanches.
