Around the new year, I wrote a quick blog post to answer for myself a question about how the natural variability in earthquake timing can effect slip rate measurements over different timescales. The results from the blog post demonstrated that there is a lot of slip rate variability over timescales …
Academic science writing (primarily journal articles) uses a rhetorical framework that lays out a portion of some scientific discipline or natural process, locates and describes the 'knowledge frontier' that bounds what is known and what is unknown, and zooms into that frontier to answer a tidy question and install a …
The belief that earthquakes release most or all of the accumulated shear stress on a fault is widespread among both scientists and the general public. It is closely related to, and may stem directly from, Henry Reid's idea of elastic rebound theory: The crust slowly accumulates elastic strain until the …
In my work as a scientist, I work on projects of a range of scales. While my major projects, which I do for work, are generally multi-year and often team-based, I also frequently start smaller projects. These are generally done to scratch an intellectual itch: quantifying a certain effect that …
Last week I was fortunate to give a presentation at the GEM Foundations's CCARA Final Workshop in Santo Domingo, Dominican Republic. The CCARA, or Caribbean and Central American Risk Assessment project, is a USAID-funded project to develop a unified seismic hazard, risk, and social vulnerability model for the region. Consistent …

Natural variability in the time between successive earthquakes on a fault leads to variability in slip rates measured over paleoseismic to neotectonic timescales. But how long does it take for the measured rates to be accurate?
While physics and mathematics have been using the ArXiv preprint/e-print repository for decades, we in the earth sciences haven't had something similar. The benefits of a widely-used preprint repository are large: it should increase the speed at which science is disseminated, reduce the stranglehold of journals on paper access …
This is a draft of a manuscript I've been trying to find a home for; it will hopefully get submitted in the next several months, but in the mean time I want to at least get the idea out there in some form. I have been working through the idea …
