Feeling the Heat: The Grilled Earth

Nowadays, there are plenty of media reports about the impacts of climate change around the world. Glaciers are disappearing, gigantic craters form in Siberia as the previously frozen ground thaws, the sea is threatening to swallow entire islands, floods cause large damages to people and economy, heat waves periodically destroy crops and can reach dangerous levels for people’s health. And this is o ...[Read More]

A lava for (almost) every colour

A lava for (almost) every colour

When we think about a volcanic eruption, one of the first things that come to our mind are lava fountains and flows with a characteristic bright orange and red colour. The colour of lavas can be associated with the temperature reached at the surface: dark red at low temperatures (475°C), orange at 900°C and white at extremely high temperature (>1150°C) (Kilburn, 2000). However, some places on E ...[Read More]

Happy blog birthday!

Listen up, everyone! The blog turns 4 year old this week! 4 years. We’ve been blogging for 4 years. Holy moly. You can finish a PhD in that time (I mean, I didn’t, but – you know – you could). We’ve had another cracking year, so let’s reflect a bit on the past year – undoubtedly one of the weirdest years in (blog) history.   What did we do? A lot. ThatR ...[Read More]

Listening to a bouquet of articles: review papers

Let me guess from which city in the world you are reading this post: Lima, Lahore or Louisville? It might be that you are modelling one of these rivers: Nile, Rhine or Lena? Or studying the Caribbean Sea, the Arabian Sea or the Caspian Sea? The country you live might be Uganda, Philippines or maybe Iceland and your home continent could well be Europe, Latin America or even Antarctica. I assume you ...[Read More]

TS Must-Read – Sylvester (1988) Strike-slip faults

Strike-slip faults by Arthur Sylvester (1988) is a must-read paper for anyone, and more so for those who want to understand the mechanisms of strike-slip faulting. Although it mostly refers to the San Andreas fault, the most studied strike-slip fault at the time (and possibly to date), the contribution is a comprehensive review of the state of the art about strike-slip faults in general. Sylvester ...[Read More]

Artificial intelligence for disaster management: that’s how we stand

On the 23rd of June, I participated in the Second Workshop for AI (Artificial Intelligence) for Natural Disaster Management that hosted around 400 scientists, UN advisors, practitioners and policymakers from all over the world interested in machine learning for supporting disaster prediction and early warning. AI is not my research area; however, I have always been interested in the new advances t ...[Read More]

The softness of ice, how we measure it, and why it matters for sea level rise

The softness of ice, how we measure it, and why it matters for sea level rise

One of the first things school children learn is that ice is a solid, and forms by freezing water. Most people think of ice as brittle–have you ever dropped a slippery ice cube on the kitchen floor, and watch it break and shatter into many pieces? It may be surprising, then, to find that ice can also stretch and squeeze, like a ball of pizza dough! Once deformed, ice is then softer in certai ...[Read More]

The Sassy Scientist – Printing: Pre- or Post-?

Giusy is throwing some deep dives into the trenches of scientific literature. Deep they are indeed. Almost running out of oxygen whilst frantically flapping through the murky waters near the surface, she comes across a not-yet-published paper (or better: a non-peer-reviewed paper) that’s floating around the internet. Apparently well-written and soundly researched, she goes looking for more a ...[Read More]

TS Must-read – Dewey (1988) Extensional collapse of orogens

After building orogens with Dewey and Bird (1970) and extending them during building with Platt (1986), Dewey (1988) explores the lifetime of orogens in their last breath: their extensional collapse. Simple considerations on how to form a normally-thick continental crust (30-40 km) from a thickened continental domain (50-60 km) indicate that erosion of the topography alone is far from being suffic ...[Read More]
