AGU and SSA have new open access policies

Open access to scientific publications and datasets is very important for both scientific progress and for the incorporation of scientific knowledge into the public sphere. The reasons for this are manifold, and have been enumerated so vociferously on various blogs, email lists, and internet fora that one fears the spittle ...

Low-angle Normal Fault Likelihood IPython Notebook

This is an IPython Notebook version of a paper I have just submitted to Geophysical Research Letters. This is the complete paper, but with all the code embedded, and is executable. However, it does need a Python module called eq_stats.py as well as some of the typical Python scientific ...

Evolution of fault stress through the earthquake cycle: a Mohr circle perspective

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 ...

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.

I'm finishing up a project estimating the maximum likelihood of observing an earthquake on a low-angle normal fault (LANF). Basically, observations ...

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.

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 ...
