A time lapse of Foursquare activity in NYC during Sandy
Nice visualization made by Foursquare of the before and after of the Sandy. It shows how check-in patterns change during an event of Hurricane Sandy’s magnitude. It all begins with the Saturday before the storm and ending early morning – the 5th of November. Besides the general ebb and flow of activity between day and night throughout the week, you’ll see the number of check-ins drastically decrease below 34th Street from Tuesday to Friday, when almost all of lower Manhattan was without power.
