Holocene Seismicity in Puget Sound: A Statistical Perspective

I presented work done with Brian Sherrod (USGS Seattle) on paleoseismologic data in the Puget Sound region of Washington at AGU. In this work, I take ~30 paleoearthquakes and estimate their magnitudes with new methods that incorporate both rupture length and measured offsets, and then calculate recurrence interval probability distributions ...

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 ...

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 ...
