I believe it's a shame that the drippings do not create the basis of a mantle-stalagmite. That would be a neat feature to study.

Is there currently any type of ground penetrating radar or other device which could physically confirm the model's output?

The abstract mentions:

> Here we present a full-waveform seismic tomographic model

So presumably, you would actually do the seismic tomography (if they haven't already). Instead of radar, you use the waves from earthquakes!
