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.
