Things to consider when interpreting Sp receiver functions…

Conversions of shear waves (S) to compressional waves (P), often analyzed as Sp receiver functions, are useful for studying upper mantle layering, and have been used to map upper mantle seismic impedance interfaces in various tectonic settings. Recently, common conversion point stacking of Sp receiver functions has revealed variations of lithospheric thickness across short horizontal …

About those amplitudes…

It is well known, at least among tomographers, that our images of the Earth’s interior are washed out. Lateral variations in seismic velocities are likely to be weaker in our models than in the actual Earth due to explicit and implicit regularization needed to obtain a solution to our mixed-determined inverse problems. As a result, …

Congratulations and Best of Luck to Sutton Chiorini!

Sutton Chiorini, who has been an undergraduate researcher in our lab for three years, has graduated and started a Master’s program at Miami University of Ohio. We wish her the best of luck in her future studies and research and will miss her engaging presence, excitement, and (s)warmth!

Pair of IRIS summer interns joins the group

This summer, we had the pleasure of hosting two summer undergraduate interns: Anant Hariharan from Cornell, and Brittany Washington from Rugters, Newark. While Anant worked on analyzing the lengthscales of heterogeneity in mantle models constructed from long and short period data, Brittany identified to sounds of whales, ice-quakes, and scraping of ice-bergs.
