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 introduces a physical model ...[Read More]

The Sedimentology of Palaeontology

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 paleontological potential. Should it prove likely that signi ...[Read More]

Who’s afraid of Natech?

Who’s afraid of Natech?

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 enormous adverse effects ...[Read More]

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

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 difference in electrical charge between the cloud and the air, nearby clouds, or the groun ...[Read More]

GeoPolicy: Don’t Look Up – could better science advice have saved the planet?

Note: Spoilers Ahead! If you haven’t already seen it, go and watch Don’t Look Up – and then come back to this blog to find out what the scientists in the film could have done to better connect and communicate with the policymakers involved! Don’t Look Up gives us a terrifying example of what could happen when policymakers ignore the science. The film tells the story of two astronomers, PhD candida ...[Read More]

The Sassy Scientist – Whining Unleashed

The Sassy Scientist – Whining Unleashed

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 though, we hear from a friend of a friend about a collea ...[Read More]

United Nations 101 for Hydrologists

Did you feel the roar of water during the 2021 United Nations (UN) Climate Change Conference (aka COP 26) hosted at the Scottish Lowlands? It was the first time that the venue had a Water Pavilion in the COP history since 1995. The hashtags #Water4Climate with #COP26 were extremely popular in the social media channels. With the elevated status of water for climate adaptation, hydrological sciences ...[Read More]
