A new method for detecting earthquakes is being developed, leveraging fiber optic cables used in global communication networks. Researchers have introduced an algorithm capable of converting these cables into seismic sensors, potentially improving early warning systems. The breakthrough could allow existing infrastructure to play a crucial role in monitoring seismic activity, including earthquakes, volcanic eruptions, and icequakes. This advancement is being explored as a means to enhance traditional seismometer networks, addressing challenges associated with fiber optic detection methods. Algorithm Integrates Fiber Optic Data with Traditional Sensors According to a study published in Geophysical Journal International, the algorithm adapts a physics-based approach to detect earthquakes using data from fiber optic cables alongside conventional seismometers. Dr. Thomas Hudson, Senior Research Scientist at ETH Zurich, told Royal Astronomical Society that fiber optic cables can serve as thousands of seismic sensors. He noted that while integrating fiber optic technology with earthquake detection has been difficult, the new approach aims to simplify the process by combining multiple data sources.
