Tsunami detection systems use a network of monitoring sensors to detect potential tsunami threats and issue evacuation warnings to potentially affected coastal areas. Although the system is vital in preventing the loss of life and property, gaps in coverage exist.

Researchers at the University of Hawaii have been working on filling those gaps, with a pilot project that turns the global network of cargo ships into a moving network of tsunami sensors.

Brilliant! I mean, they are already out there…

Photo by Daniel Ramirez (CC 2.0) Researchers from the University of Hawaii, funded by the National Oceanic and Atmospheric Administration (NOAA), are partnering with the Matson and Maersk shipping companies and the World Ocean Council to equip 10 cargo ships with real-time high-accuracy GPS systems and satellite communications.


Each vessel will act as an open-ocean tide gauge. Data from these new tsunami sensors are streamed, via satellite, to a land-based data center where they are processed and analyzed for tsunami signals. Read more from here…
