Introduction to the principles of brittle faulting and earthquake mechanics with emphasis on physical processes.

Brittle failure, effective stress laws, friction, constitutive laws, continuum mechanics, and elasticity of faulting. Rate and state friction laws. State of stress in Earth's crust. Fault nucleation and growth. Fault rocks and structures. The strength and rheology of faults. Seismotectonics. Introduction to earthquake rupture. Instability conditions, energy balance, the work of faulting. Quantification of earthquakes. Earthquake source parameters and scaling laws. The seismic cycle, earthquake prediction.

Problem Sets:
Statement about authorship and working together.
For our problem sets, my sense is that there is significant value in working together at some level. Explaining things to someone else, or having them explain things to you is useful. Of course there's a limit. Copying down someone else's answers and/or paraphrasing their thinking, even if you use your own approach, is generally much less useful than doing your own work.
So, please do seek each other out as a way to learn. Getting a bit of help to get started or past a sticking point is fine, with the idea that you move on from there on your own and, ultimately, work it out yourself.
Problem Set 1, Due 5 Sep.
Problem Set 2, Due 12 Sep.
Problem Set 3, Due 28 Sep.
