The National Geographic documentary programme Seconds From Disaster investigates historically relevant man-made and natural disasters from the 20th century. Each episode aims to explain a single incident by analyzing the causes and circumstances that ultimately affected the disaster. The program uses re-enactments, interviews, testimonies, and CGI to analyze the sequence of events second-by-second for the audience. National Geographic has broadcast many of the programme's episodes under multiple titles. The title currently or most recently listed on the NGC Calendar is shown first. Alternate titles are shown in parentheses.
