The Internet, mobile telephony and mobile have radically changed the way people behave in emergencies and disasters across the world. In particular they have given people new tools and opportunities to find and help each other. From the Humanitarian OpenStreetMap team building maps on the fly in the developing world, through mobile charging stations for refugees to self organised responses to natural and man-made disasters. Communities across the globe are becoming more resilient and with the application of AI, robotics and drone technologies the outlook is, surprisingly for such a depressing subject, positive.
