Offline telecom cables called \u201cdark fibres\u201d can be used to sense underground seismic waves. Geophysicists are increasingly using such signals to study aspects of Earth\u2019s subsurface, including hidden sources of geothermal energy and earthquake hazards.<\/p>\n

\u201cIf a large earthquake happens on the fibre on which we are speaking, the frequencies in my voice would be slightly distorted,\u201d Andreas Fichtner<\/a> at ETH Zurich in Switzerland told New Scientist<\/em> on a video call.<\/p>\n
