Try this on for seismography: Fiber optic cables could soon have another purpose -- detecting earthquakes.

Fiber optic isn’t just the future of the internet — it could also be the future of seismography.

New research emerging from Stanford University suggests that we may soon be able to leverage those fiber optic networks not only to deliver high-speed connectivity to homes and businesses, but also to continuously monitor and study earthquakes.

Professor Biondo Biondi, a professor of geophysics at the California institution, has led an effort to “convert the jiggles of perturbed optical fiber strands into information about the direction and magnitude of seismic events,” as per a Stanford press release.

Over the last year, researchers have been taking note of seismic disturbances in a 3-mile loop of optical fiber located underneath the university’s campus.

These disturbances have been recorded with instruments called laser interrogators, which come from a company called OptaSense (OptaSense is assisting with the research).
