Measuring Earthquakes and Tsunamis with Fiber-Optic Networks

For wealthy countries like Switzerland, having a dense network of earthquake monitoring stations is a matter of course. This is not the case in less developed countries and on the floor of the world’s oceans. While poorer regions lack the money for the necessary number of sensors, the oceans require complex systems that can reliably measure minimal pressure changes at depths of thousands of meters and bring the data signals to the surface.
