Invited Talk Prof. Sonia Martín López

Distributed Acoustic Sensors 

(DAS) for Seafloor Seismic Monitoring:

from earthquakes to tsunamis

---

In recent decades, the massive use of telecommunications has driven the need to lay millions of kilometers of optical fiber cables all over the planet, particularly in the oceans. Recent developments in the field of fiber optic sensing have revealed the possibility of transforming all these cables into powerful arrays of geophysical sensors, capable of measuring variables such as deformation and temperature with high sensitivity, over tens of kilometers of distance and providing spatial information. This talk will review the key technological aspects behind these systems, with special attention to the performance achievable in this application scenario.
