Dear colleagues,

We would like to kindly invite you to contribute an abstract to the Symposium "Frontiers in Fiber-Optics Sensing in Seismology" of the IAGA/IASPEI Joint Scientific Meeting that will be held 31 August - 5 September in Lisbon, Portugal.

Please find the full description of the Symposium below and on the IAGA/IASPEI 2025 online portal: https://iaga-iaspei-2025.org/iaspei-symposia/.

The session will span a wide range of topics related to the use of fiber-optic sensing technologies (e.g. Distributed Acoustic Sensing, laser interferometry, state of polarization) in the field of seismological investigations. We invite contributions including but not limited to: methodological and instrumentation advances, novel processing and data handling approaches, case studies, etc.

Please note that the deadline for submission of abstracts and travel grant applications is Wednesday 12 March 2025, 23:59 Pacific Time.

We are looking forward to your contributions and to meeting you in Lisbon!

Best regards,

The convening team: Verónica Rodríguez Tribaldos, Hsin-Hua Huang, Cecilia Clivati, Meghan Miller

S05 Frontiers in Fiber-Optics Sensing in Seismology

In recent years, a wide variety of fiber-optic sensing technologies have emerged as a novel and revolutionary tool in seismology. Distributed Acoustic Sensing (DAS) converts fiber-optic cables into ultra-dense arrays of seismic sensors that can record the unaliased seismic wavefield along distances of 10’s of km, providing opportunities for local and regional subsurface imaging and monitoring at unprecedented spatial resolution in challenging environments such as boreholes, urban areas, volcanoes, or glaciers. Novel approaches based on the analysis of optical phase changes from ultrastable laser signals, the state of polarization (SOP) of regular telecommunication traffic, or optical phase changes obtained as by-product of phase-noise cancellation (PNC) approaches routinely conducted in metrological networks are extending the range of fiber sensing to several 1000s of km, demonstrating the potential of transoceanic fiber-optic cables as a tool to improve earthquake detection and early warning offshore. Along with technological developments, advances in data processing and analysis methods, machine learning approaches and numerical modeling tools enable mining these new, and sometimes massive, datasets.
This session will span a wide range of topics related to fiber-optic sensing methods in seismology and geophysics, including but not limited to: developments in theoretical and methodological aspects of fiber-optic sensing, novel processing and data handling approaches, case studies from fiber-optic sensing experiments worldwide, and insights gained from fiber-optic sensing measurements in the context of other types of seismological/geophysical datasets. We invite contributions from research related to all aspects of fiber-based sensing.
