Linking distributed and integrated fiber-optic sensing
Daniel C. Bowden, Andreas Fichtner, Thomas Nikas +7
Distributed Acoustic Sensing (DAS) has become a popular method of observing seismic wavefields: backscattered pulses of light reveal strains or strain-rates at any location along a…
Sensitivity kernels for transmission fiber optics
Andreas Fichtner, Adonis Bogris, Daniel Bowden +6
Fiber-optic sensing technologies based on transmission offer an alternative to scattering-based Distributed Acoustic Sensing (DAS). Being able to interrogate fibers that are thousa…
Introduction to phase transmission fibre-optic sensing of seismic waves
Andreas Fichtner, Adonis Bogris, Thomas Nikas +6
This manuscript is concerned with phase changes of signals transmitted through deforming optical fibres. As a first result, it establishes an exact relation between observable phas…
Microwave frequency dissemination systems as sensitive and low-cost interferometers for earthquake detection on commercially deployed fiber cables
Adonis Bogris, Christos Simos, Iraklis Simos +6
We experimentally demonstrate a microwave frequency dissemination system operating as a sensitive interferometric sensor of seismic waves on commercially deployed fiber networks in…
Post-spontaneous-symmetry-breaking power-laws after a very strong earthquake: Indication for the preparation of a new strong earthquake or not?
Stelios M. Potirakis, Yiannis Contoyiannis, Konstantinos Eftaxias +2
It has recently been found that the evolution of the preparation of a strong earthquake (EQ), as it is monitored through fracture-induced electromagnetic emissions (EME) in the MHz…
Pre-earthquake electromagnetic emissions with critical and tricritical behavior before the recent Durrës (Albania) (Mw=6.4, 26-11-2019) and Chania (Greece) (Mw=6.1, 27-11-2019) earthquakes
Stelios M. Potirakis, Yiannis Contoyiannis, Grigorios E. Koulouras +3
In this brief report we present evidence for the dynamics of the earthquake (EQ) preparation processes that led to two strong events (Mw>6) that took place in Durrës (Albania) and…
Preliminary results concerning the fracture-induced electromagnetic emissions recorded prior to the Mw 6.7 Earthquake on October 25, 2018 south of Zakynthos
S. M. Potirakis, Y. Contoyiannis, N. S. Melis +5
In this letter we present preliminary results concerning precursors to the recent significant (Mw 6.7) earthquake (EQ) that took place in the region south of the Greek Island of Za…
