- Remember: Due Date for final reports is: December 12, 9 am: Report of no more than 8 pages length (total, including text (1.5 spacing, font >11 point), figures, tables, references)--remember the famous Pascal quote: "If I had more time I would have written a shorter letter."
- Remember: December 13 12:20-2:10 pm: Final class meeting; 5 minute Powerpoint presentation (5 slides or less). It would make our lives easier if you could email or put somewhere convenient for me the powerpoint of your talk in advance of the final class meeting so we don't lose time in the transitions between speakers. Also: I expect you to not go over the time. Practice your talk and make detailed slides that will help you tell your story. A short talk can be full of information. Don't sell yourself short, but be efficient and compact in your delivery.
December 1, 2005
- I have updated our Lectures page to catch up with the prior lectures. I put a bunch of Poly3D links there and on our Links page.
November 10, 2005
- I have modified a few of the due dates and the paper length for the final project (GLG510--Final_Project.html).
- I have now contacted all of you with my review of your final project proposal.
- No class on Tuesday, November 15. Monday I will be at USC for a colloquium and then I will be visiting UCLA Tuesday and meeting with the tectonics colleagues there.
November 3, 2005
- I have postponed the due date for Exercise 3: Simple dislocation models for earthquake displacements and the earthquake cycle to Thursday, November 3 UNTIL 6 pm today for the Izmit earthquake coseismic and postseismic parts and UNTIL Tuesday at the beginning of class for the Alaska parts. I will give some extra credit for turning the whole thing in today.
- Here are a couple more hints for you:
- For Izmit coseismic, the depth is not as deep as the 1906 example I did in the Clarifications and hints for the dislocation exercise.
- Izmit postseismic:
- For Izmit postseismic, depth to the top controls the width of the peaks of the displacement field. So, first do trial and error to find out what width of peaks you need by changing the depth to the top (how it drops back to zero will be controlled by how deep it is to the bottom, but it will be much less sensitive to that--make it at least a few km tall (height of fault)).
- The Izmit postseismic displacements are a bit assymetric (they imply less slip and shallower top of rupture on the negative side). We cannot handle that with this model, so just split the difference.
- Great Alaska Earthquake:
- Coseismic: It will be hard to fit the points between 400 and 500 km with the coseismic tip at 354, so try your best. It is probably good to ignore the high magnitude point at 353.85 and so you should really try to fit the points from 365.38 and further south.
- Coseismic: As in the postseismic for Izmit, first figure out what the effect of changing the length of rupture does (locates max subsidence). Then, once that is pretty well located, then by trial and error, find the slip that fits the data the best.
- Postseismic: build this one slowly by first constructing the upper fault, then the lower fault. Make sure you account for the different dips (for the slip rate and the fault geometries). Assume that the lower fault is at least 50 km long (or goes to about 100 km depth).

- No Field Trip; I cannot get everyone together for a free weekend: frees up 11/19 and 11/20.
- Don't forget that you need to give me some information about your final project plans on Thursday: GLG510--Final_Project.html

- Field trip date is now in flux. Stand by for an update.
- I have handed out Chapter 7 from Ragan and Arrowsmith. Please read through it. We will not have a quiz on Tuesday, but be prepared to continue our lessons on vectors based on it.
- I have updated somewhat the class schedule. I am unsure of the details week-by-week because I don't want to rush too much and want to think carefully about what we cover and how much. But, some things are clear: we probably won't meet during the week of AGU (12/6 and 12/8), but we will probably meet during our Final Exam time for final student presentations. More information on final projects will come shortly.
- I have placed the two matlab files that we built in class for the rotation example on the class web site in the Matlab Lecture. Use them to help you to set up your homework.
September 8, 2005
- We did not quite get to where I wanted to be to make the homework assignment for MATLAB in the Introduction to Matlab, so the homework is not assigned yet. But, I do expect that you will go through the following documents in particular. Remember that this is the best way to learn: go through and follow the steps, watch for the little tricks that we mention, and work on building scripts and functions.
- No class meeting Tuesday, September, 13! A group of us will be at the Southern California Earthquake Center Annual Meeting. Use that time to complete your assignments.

- I added Chapter 7 from Ragan and Arrowsmith to the Links page.
- Grading for quiz 1 (20 points total): Check: basically ok, but does not demonstrate strong knowledge of text (15 points); Check minus: not much there (5 points); Check plus: clearly read and answered the questions demonstating knowledge of the text (20 points); Check plus plus: went above and beyond and even busted out some equations! (25 points). Try to put a good effort into the reading!
- Field weekend will be November 19 and 20 (see the schedule. Please keep that weekend available.
- My office hours are by appointment. Don't be afraid to just email me or call me and make an appointment. I can be sure I will have the time to help you out.
August 27, 2005
- I contacted the editor at Cambridge University Press to complain about the delay in our textbook delivery. Here was our exchange. It looks like they will be here about September 14.
August 25, 2005
- I ordered 20 textbooks, so there should be enough.
- I am working on bugging them to get it delivered as soon as possible.
- I updated the class schedule. It is still tentative and subject to change.
- I uploaded today's lecture.
