Everything’s Coming Up Roses for Pasadena Seismologists
Using fiber-optic cables, a new seismic network charts vibrations associated with the Rose Parade’s massive floats and marching bands.
Fiber-Optic Networks Find a New Use as Seismic Sensor Arrays
Distributed Acoustic Sensing: Principles and Case Studies; Washington, D.C., 9 December 2018
Unused Fiber-Optic Cables Repurposed as Seismic Sensors
So-called dark fiber can serve as regional seismic activity monitors and also detect earthquakes thousands of kilometers away, according to new research.
Fiber Optics Opens Window into Subsurface Deformation
The distributed deformation of buried materials is difficult to map, but a new approach is able to resolve vertical deformation over the length of a fiber optic cable.
Fiber-Optic Networks Can Be Used as Seismic Arrays
A new study repurposes telecommunications cables to harness sound from light. The method can accurately measure ground motion from distant earthquakes.
Fiber Optics Can Improve Borehole Measurements
Scientists demonstrate the potential of fiber optics to measure fluid flow in boreholes as an alternative to traditional measurement techniques.
