Adjoint Tomography Illuminates Hikurangi Margin Complexity

by Michael Bostock 21 April 202227 January 2023

Waveform inversion of regional earthquakes reveals velocity anomalies interpreted as subducting seamounts that control an enigmatic segmentation in plate coupling along the Hikurangi margin.

Improved Seismic Imaging Via Optimal Transport Theory

by Michael Bostock 7 July 202110 March 2022

Seismic waveform inversion is inherently non-linear. New objective functions based on optimal transport theory mitigate nonlinearity yielding stable solutions without need for accurate initial models.
