# Topographic and tectonic stress inversions with halfspace: Preparing a DEM

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.

# DEM Prep

This is a brief step that simply involves reading and flipping a DEM ...

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.

## Scientific Python installation

The first step in using halfspace for topographic stress calculations is to ...

# Halfspace: a Python package for elastic halfspace calculations

## 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 written a Python ...

# 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

In my recent work on topographic stresses and their interaction with faulting, I have been thinking a bit about what stresses look like on a fault during the earthquake cycle. I wrote this IPython notebook to explore this topic a little bit.
