Constraints on Seismic Anisotropy in the Mantle Transition Zone from Long-Period SS Precursors
The mantle transition zone (MTZ) of Earth is demarcated by solid-to-solid phase changes of the mineral olivine that produce seismic discontinuities at 410 and 660 km depths. Mineral physics experiments predict that wadsleyite ...
The Seismic Signatures of Recently Formed Impact Craters on Mars
(Journal of Geophysical Research Planets, 2019-09)
We investigated the seismic signatures of recent impact crater clusters on Mars that would be recorded by the InSight Seismic Experiment for Interior Structure (SEIS) seismometers. We used a database of 77 measured and ...
