Topographic and tectonic stress inversions with halfspace: Calculating topographic stresses on a fault

In order to complete the tutorial, please first clone/download the github repo which comes with the DEM, coseismic slip model, and some auxiliary files, all with the correct pathnames.

(Or just download this notebook)

This part is pretty easy. It's just an interpolation of the topographic stress field \(M …

Topographic and tectonic stress inversions with halfspace: Calculating the topographic stress field

edited 22 Feb 2015: Equations \(G_{xx}^B\) and \(G_{yy}^B\) corrected

Background of the topographic stress field calculations

The weight of mountains (or other high topography) induces stresses in the earth below the topography. Unlike many other types of stress in the crust, topographic stresses are expected to …

Halfspace: a Python package for elastic halfspace calculations

(edited 4 October 2014)

Part 1: Introduction

I've been working the past year and a half on calculating topographic and tectonic stresses. This work has relied heavily on using elastic halfspace approximations, which are quite commonly used in the crustal deformation communities, particularly by geodesists. To this end, I have …

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 …
