Detecting earthquakes with Fibre Optics

How a system designed to carry TV and internet traffic can help detect earthquakes

Los Angeles is famously earthquake prone, but it is also known for its technological advancement, being close to the heart of the computer industry. Seismologists have developed a new system which uses redundant capacity on fibre optic networks across the city to detect earthquakes.

Also in the programme the end of Opportunity – the legacy of the Mars Rover designed to have a working life of just 3 months, which continued to explore the Martian surface for 14 years.

And we look at fish and coral. How best can coral reefs be encouraged to regrow after destructive extreme weather events, and why fish farming may be a useful conservation tool as well as a lucrative business.
