Hazards
Submarine geological hazard
The aim of the project was to gain and disseminate knowledge on the industry challenge of why exactly, how often, and where are seafloor cables broken by natural causes, primarily subsea landslides and sediment flows. The global economy relies on uninterrupted usage of a seafloor network of telecommunication cables that carry ~99% of all inter-continental digital data traffic. Multiple cable breaks in important regional hubs can have major implications, and repairs can cost up to £100 million.
