# Seismic Seconds

Seismic Seconds is a documentary television series that aired in the late 1990s on the National Geographic Channel. The program analysed the causes of six incidents, five involving the loss of human life. The better-known sequel to Seismic Seconds, Seconds From Disaster, was spun off from the series.
In the British version, the narrator says in the voiceover:
   Disasters don't just happen. They're the result of a sequence of events, locked together in time. The science behind what went wrong is hidden in those seismic seconds.
The beginning of this voiceover:
   Disasters don't just happen. They're the result of a sequence of events
was later used and modified for the series Seconds From Disaster:
   Disasters don't just happen. They're the result of a critical chain of events.
