Abstract

The Earth's surface is 70% covered by water, yet the coverage of seismometers in oceans remains limited. A cost-effective solution to enhance seismic detection is to leverage the existing submarine fiber optic network, originally deployed for telecommunications. This study conducts a systematic review of seismic detection techniques using fiber optics, analyzing research published since the year 2000. The main objective was to identify the most commonly used techniques and assess their applicability. The Scopus database was consulted, and 24 articles were selected from an initial set of 596 through a systematic process. The PICO framework guided the analysis of primary sources. The results indicate that Distributed Acoustic Sensing (DAS) is the most widely employed technique. Additionally, most studies were found to be concentrated in the Northern Hemisphere. The study concludes that DAS is a promising approach for developing seismic event early warning systems and mitigating their impacts.
