Predicting earthquakes and tsunamis with fiber-optic networks

Geophysicists at ETH Zurich have shown that every single wave of a magnitude 3.9 earthquake registers in the noise suppression system of fiber-optic networks. This method, now published in Scientific Reports, can be used to set up close-meshed earthquake and tsunami early warning … | Continue reading
