In the 1830's, William Miller and his group of Second Adventists put their faith on the return of Christ in 1844. It became known as the "great disappointment" but the faithful kept faithful. They later concluded that Christ's return was invisible (sound familiar? - C.T. Russell borrowed many of our beliefs from Adventism).
This group later became known as the Seventh-Day Adventists. The strictly conservative Aventists now - 180 years later - number over 18 million. Still keeping the faith. Still adjusting their daily lives to the tenets of this religion.
For the past 2000 years, apocalyptic millennialist sects have used disasters (human or natural) as proof of the coming end. This won't ever end as long as there are people willing to put their trust in those ideas.
