[iris-bulk] Coulomb 3.0 Short Course on Sat Dec 8 at the USGS

[IRIS]

Coulomb is designed to investigate Coulomb stress changes on faults,  
dikes,
and earthquake nodal planes, and is intended for publication-directed
research and university teaching and instruction

The program, user guide, and tutorial files are freely available from:

Taught by Ross Stein (USGS), Shinji Toda (AIST), Jian Lin (WHOI), and  
Volkan Sevilgen (USGS), this free, full-day, course is guaranteed to  
turn novices into mavens. You don’t have to take the class to use  
Coulomb, but you will learn faster with us. You'll use your own  
laptop and receive a bound User Guide. We have room for only 50  
people. To register for the course, contact vsevilgen at usgs.gov (650  
329 4803); your place is reserved if you get a confirmation email.  
Coulomb runs on Mac’s (PowerPC or Intel), Windows PCs, and Linux. It  
is a MATLAB application, so you’ll need to install MATLAB 7.X before  
arriving, or use our demo license to take the class.

Why Coulomb?

We believe that people learn best when they can see the most and can  
explore alternatives quickly. So the principal feature of Coulomb is  
ease of input, rapid interactive modification, and intuitive  
visualization of the results. Coulomb calculates displacements,  
strains, and stresses caused by fault slip, magmatic intrusion or  
dike expansion. Problems such as how an earthquake promotes or  
inhibits failure on nearby faults, or how fault slip or dike  
expansion will compress a nearby magma chamber, are germane to  
Coulomb. Geologic deformation associated with strike-slip faults,  
normal faults, or fault-bend folds is also a useful application.  
Calculations are made in an elastic halfspace with uniform isotropic  
elastic properties following Okada (1992). The internal graphics are  
suitable for publication, and can be imported into illustration or  
animation programs for enhancements.

Course Structure

In the morning, we’ll introduce you to Coulomb analysis and explain  
our approach to modeling through a series of animations and slides.  
Then you'll learn how to build and use input files, add active fault,  
earthquake catalog, and coastline overlays. Then you'll calculate  
displacements and strains, and create publication-quality PDF and  
numerical output files. We’ll also show you how to taper or tile the  
fault slip, and how Coulomb can read the leading database of variable- 
slip source models. In the afternoon, we’ll focus on Coulomb stress  
analysis for seismic and volcanic investigations, and show you how to  
display your results in Google Earth. You'll resolve stress changes  
on faults in their rake directions, on specified rakes, or on optimal  
planes. You’ll learn how to view all these results graphically in 3D  
and output numerical tables. With five instructors, there will be  
plenty of individual attention, and no one will be left behind.

Course Logistics

The USGS campus is 50 minutes south of San Francisco by car, or 1 hr  
by train. Take the 8:00 AM train (#442) from the San Francisco  
station at 4th St and Townsend. We will pick people up at the Menlo  
Park train station. The course runs from 9:00 AM to 5:00 PM. A  
catered lunch and refreshments that will cost you $15 will be served.
