Earthquake-coda Tomography Boosts Illumination of the Deep Earth

by Andreas Fichtner 28 May 202027 January 2023

A new tomographic method based on correlations of seemingly chaotic earthquake coda waves yields otherwise unobservable arrivals, thus greatly improving illumination of the deep Earth.

Seismological Models Are Biased, but Scientists Have a Solution

Shannon Hall by S. Hall 26 September 201629 September 2016

Many seismic wave models are based on an erroneous assumption about the Earth's interior. A new technique corrects this by eliminating false signals produced by models.
