# Estimating stresses, fault friction and fluid pressure from topography and coseismic slip models -- AGU 2014 Presentation

For the AGU Fall Meeting 2014, Eric Hetland and I presented a summary of our recent work on stress and fault property estimation in seismically active areas with high topography. Much of this work is featured in a forthcoming Journal of Geophysical Research paper (focusing on the 2008 Wenchuan event ...

# 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.

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

# 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 ...

# 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:
