The principles of imaging complex structures in the Earth subsurface using 3-D reflection seismology. Emphasis is on processing methodologies and algorithms, with examples of applications to field data. Topics: acquisition geometrics of land and marine 3-D seismic surveys, time vs. depth imaging, migration by Kirchhoff methods and by wave-equation methods, migration velocity analysis, velocity model building, imaging irregularly sampled and aliased data. Computational labs involve some programming. Lab for 3 units. Offered every year, Spring quarter.

GEOPHYS 281: Geophysical Inverse Problems
Concepts of inverse theory, with application to geophysics. Inverses with discrete and continuous models, generalized matrix inverses, resolving kernels, regularization, use of prior information, singular value decomposition, nonlinear inverse problems, back-projection techniques, and linear programming. Application to seismic tomography, earthquake location, migration, and fault-slip estimation. Prerequisite:

GEOPHYS 286: Global Seismology
This course investigates how waves propagate through the whole Earth. This course examines the questions "How do body waves and surface waves behave within the Earth?" and "What does that tell us about the Earth?" The course delves into both theory and how we apply that theory to understand seismic observations. Requirements:
Math 52 or
CME 102, GP130 or permission from instructor.
Instructors:
Lawrence, J. (PI)
GEOPHYS 287: Earthquake Seismology
Seismic wave propagation (body waves and surface waves, reflection/transmission), Green's functions, seismic moment tensors and equivalent forces, representation theorem, finite-source effects. Prerequisites:
GEOPHYS 130 or equivalent. Offered every other year, spring quarter.
Terms: Spr

GEOPHYS 290: Tectonophysics & Global Tectonics (GEOPHYS 186)
The physics of faulting and plate tectonics. Topics: plate driving forces, lithospheric rheology, crustal faulting, and the state of stress in the lithosphere. Exercises: lithospheric temperature and strength profiles, calculation of seismic strain from summation of earthquake moment tensors, slip on faults in 3D, and stress triggering and inversion of stress from earthquake focal mechanisms. Offered every other year, winter quarter. This course is offered in 2014-15 instead of
Geophys 170/220.
