Scientists from the University of Malta, INRiM and INGV presented results related to the SENSEI project the last week of August during the IAGA/IASPEI* Joint Scientific Meeting 2025 organized in Lisbon (Portugal)

• The University of Malta and INRIM, in collaboration with the Maltese telecom company Epic and scientists from Ifremer, MBARI, and Dalhousie University, presented results on the use of laser phase interferometry for monitoring oceanographic and offshore geological events using a telecom cable deployed in the Mediterranean Sea between Sicily (Italy) and Malta. Thanks to its long reach, manageable data size, and coexistence with telecom data transmission, laser phase interferometry appears suitable for long-term monitoring, potentially allowing observation of seasonal trends and rare events.

• INGV presented results on the possibility to improve the earthquakes’ localization using fibers in addition to conventional seismometers. Their study was conducted on a set of synthetic events. After the first promising results, the team of INGV will now proceed on real data recorded with fibers on the SENSEI testbeds. 

* IAGA (International Association of Geomagnetism and Aeronomy) and IASPEI (International Association of Seismology and Physics of Earth’s Interior) are associations of the International Union of Geodesy and Geophysics (IUGG), dedicated to advancing the study of earthquakes, seismic sources, wave propagation, and the Earth’s internal structure and processes.
