sources, magnitude moment tensors and focal mechanisms,
plate motions.
III. Seismology: Kinematics -- travel times, velocities,
earth structure,radially symmetric structure, 3-D structure
and tomography.

isostasy.
V. Geothermometry -- heat flow of the earth, temperature
distribution (geotherm), thermal structure of mid-ocean
ridges and trenches, whole mantle convection.
VI. Geomagnetism -- magnetization of rocks, magnetic field
of the earth and its secular variation, dynamo theories,
core formation and structure.
