Numerical Modeling of Mantle Flow Beneath Madagascar to Constrain Upper Mantle Rheology Beneath Continental Regions

Published in Journal of Geophysical Research, Solid Earth, 2019

This paper is about elucidating the source mechanism of the observed complex azimuthal seismic anisotropy beneath Madagascar. This study yields better understanding of mantle flow beneath Madagascar and the mantle rheology beneath continetal regions.

Localization of Large Intraplate Earthquakes along Faulted Deep-Reaching Density-Contrast Boundaries: Insights from the 2017 Mw6.5 Botswana Earthquake

Published in Journal of African Earth Sciences, 2023

This paper is about the how crustal-scale density contrast boundaries concentrate strain and localize intraplate earthquakes.
