This week's programme in the series on Man and Science Today.

San Francisco is, literally, a city that waits to die. It faces destruction from an earthquake which, scientists warn, could kill 100,000 people. The earthquake is inevitable and imminent, and yet it's claimed that there has been a scandalous neglect in applying already existing knowledge to reduce hazards.

Five thousand children, for example, go to schools sited directly on the actual earthquake faults and in the earthquake predicted those children will be killed.
Tonight's Horizon tells the story of the small group of scientists who, in a struggle against apathy, are trying to save their city. They are also involved in crucial experiments which are already enabling them to predict some earthquakes and which in the near future will enable them to realise the hitherto science-fiction dream of preventing earthquakes.
