Seismic monitoring using the telecom fiber network

S. Donadello, C. Clivati, et al.

This groundbreaking research by Simone Donadello, Cecilia Clivati, Aladino Govoni, and others unveils the capability of laser interferometry on fiber optic cables to monitor seismic activity. The study demonstrates the detection of earthquakes over a vast magnitude range using innovative techniques, paving the way for new applications in both local and global seismic monitoring.

Abstract
This research paper explores the use of laser interferometry on telecommunication fiber optic cables for seismic monitoring. The authors analyze 1.5 years of data from a 39km land-based fiber optic cable in Italy, comparing it to data from co-located seismometers. They successfully detect earthquakes across a wide magnitude range, even very weak ones, and establish relationships between detection probability, magnitude, and distance. Spectral analysis of the fiber data provides insights into earthquake dynamics. The study confirms the potential of this technique for both global and local seismic monitoring, with applications for civilian purposes.
