$TS Must-Read – Cowie and Scholz (1992) – Physical explanation for the displacement-length relationship of faults using a post-yield fracture mechanics model$

The Must-Read paper by Cowie and Scholz (1992) uses theory from fracture mechanics to explain fault growth and fault displacement profiles. The article initially points out the weaknesses in previous work, specifically highlighting how the abrupt termination of displacement profiles at fault tips would imply an infinite stress in the surrounding material. The paper then …[Read More]

The Sedimentology of Palaeontology

Jon Noad February 8, 2022

A chance to reflect Over the last year, I have been lucky enough to spend more than two months in the field examining a variety of outcrops representing terrestrial, glacial and marine depositional settings. To protect Alberta’s fossil heritage, the law demands that all sites where excavation will be undertaken must be assessed for their …[Read More]

Who’s afraid of Natech?

Giulia Roder February 7, 2022

Natural hazards that impact industrial sites and result in technological accidents, causing the release of hazardous substances, are referred to as Natech events. In the popular imagination, Natech accidents are triggered by major natural hazard events. However, experience tells us that low magnitude natural events, such as lightning or heavy rains, are sufficient to cause …[Read More]

Did you know… Arctic lightning strikes are on the rise?

Jenny Turton February 4, 2022

When we think of lightning, it is often accompanied by warm summer nights, tropical storms and a sticky feeling when we try to sleep. However, lightning also happens in the cold Arctic, and is even increasing in frequency. But how and why? And why does that matter? What is lightning? Lightning is caused by a …[Read More]

The Sassy Scientist – Whining Unleashed

The Sassy Scientist February 4, 2022

We are all underpaid and underappreciated. That is almost the dictionary definition of academic jobs. We bounce from one barely acceptable contract to the next, hoping to finally land a tenure-track position that allows us to swim in money like Scrooge McDuck. But before that, science itself should be its own reward and sustenance. Sometimes …[Read More]
