Topographic Stresses and the 2008 Wenchuan, China earthquake -- AGU 2013 Presentation

For the AGU Fall Meeting 2013, we (myself, Eric Hetland, Guohong Zhang) presented a talk on stresses resulting from high topography and how those stresses can influence faulting. The presentation focused on the 2008 Wenchuan, China earthquake. Here is the slideshow:

The influence of topographic stresses on faulting, emphasizing the …

Some tips for new scientific programmers

This post is slightly modified from an email that I wrote to some friends who were looking for tips on getting started with scientific computing with MATLAB. I'm not the world's expert on the subject, and I traded MATLAB for Python a couple years back, but the advice should be …

A new open-source GIS file for active(?) low-angle normal faults

TL;DR: I made a GIS file (SHP, KML, GeoJSON) of potentially-active low-angle normal faults. You can get it at github here, and contribute if you'd like.

A MathJax sample

This post is a quick mathjax test.

$$ P(A | \sim O) = \frac{P(\sim O|A) P(A)} {P(\sim O|A)P(A) + P(\sim O|\sim A)P(\sim A)} $$

That was easy.

Active Tectonics of the Andes (ATA) active fault database now on GitHub

This post originally appeared on my old blog.

In order to facilitate collaboration in development of the Active Tectonics of the Andes, a database of active faults in the (northern, for now) Andes, we have hosted it on GitHub. The development version is here, although the ‘release’ versions will continue …

Article on the South Lunggar rift, western Tibet, accepted in Tectonics

This was a post that originally appeared on my old blog

A big part of my PhD was the exploration of a large, but essentially unknown, active rift in southwest Tibet, the South Lunggar rift. We mapped the rift, and did a solid amount of zircon (U-Th)/He thermochronology, combined …

HimaTibetMap now on GitHub

This was a post that appeared on my old blog.

edit 9 June 2013: HimaTibetMap repo on GitHub updated to new address

I maintain HimaTibetMap, an open-source database of active faults in the Indo-Asian collision zone. While I was in phd school, we hosted the data on KU’s proprietary …

Active Tectonics of the Andes (ATA-1.0): A new open-source active fault database, and interpretation

This post originally appeared on my old blog. Please note that the ATA database is now located at GitHub.

The 1 October 2012 issue of GSA Today (a science and news magazine by the Geological Society of America) features a new article from our research group, primarily written by my …

Great BBC documentary on Youtube of mountain building and collapse highlighting Tibet

This was a post that originally appeared on my old blog.

I was sent a great BBC video entitled ‘Roof of the World’ that does a nice job of outlining many of the modern concepts of mountain building (orogeny) and related collapse (taphrogeny), with emphasis on the Tibetan/Himalayan system …
