The P-wave RUM model. Velocity profiles corresponding to each tectonic region.
Project Description
Global tomographic images correlate
strongly with major tectonic features.
The level of velocity variations is highly
concentrated in the upper mantle and
most globally recorded earthquakes occur
in, or around, subducting slabs. This leads
us to a new strategy in global tomography.
We insert a-priori information
by designing an irregular parameterisation
which incorporates these observations.
We simultaneously invert for 1-D P and S-velocity models inside each tectonic region of Earth, each defined with by iregular 3-D parameterization. A description of the RUM project with figures and results can be found by clicking here .
