In 2014 when my city was innundated with floods and no electricity meant internet was hard, I tracked down a photo posted online using exif data to inform another person that the photo was of his neigbourhood and that the photo was taken at a particular time. I remember spending days/weeks 18 hours a day cold calling all my contacts one after the other because I wanted to "hear someone say they are alive". In the end everything worked out pretty fine and a major disaster didnt happen.
