Wait, I could do geophysics—physics and math—and go outside?! That's the perfect combination.

Exploring a Changing Continent Using a Plate Boundary Observatory


Geodesy is the science of measuring the size, shape, and gravity field of Earth, and how these change with time.

(a) Physics-based conduit model.  (b) Some depth-dependent properties inferred by solving the physics-based conduit model.  As magma ascends and depressurizes, the solid volume fraction increases due to crystallization, in part causing the velocity to change from viscous flow to frictional sliding.
