Earthquake of the month: Bransfield Basin – Antarctica M 5.4

Earthquake of the month: Bransfield Basin – Antarctica M 5.4

As well as August, September was not highlighted by a large event (> M 7). The TOP 3 strongest earthquakes which occurred during this month correspond to a strike-slip earthquake in the Mid-Atlantic Ridge (M 6.9), an interplate EQ in central-north Chile (M 6.8), and another EQ in a different segment of the Mid-Atlantic Ridge (M 6.7). Furthermore, the largest event in Europe occurred on Septembe ...[Read More]

Can we connect the exceptional floods in France and Italy associated with the storm Alex to climate change?

The first days of October were marked by an extreme weather event: storm Alex, a cyclone of Atlantic origin, caused massive showers and thunderstorms over Provence, the Alps, Piedmont and Liguria. In these regions, numerous historical records of precipitation were broken causing the flooding of several streams and rivers in which many people lost their lives. Economic damage was also significant a ...[Read More]

Interactive and Collaborative Virtual Reality Visualization for Geodynamics

Interactive and Collaborative Virtual Reality Visualization for Geodynamics

Nowadays geodynamics can involve a lot of 3D data which has to be analyzed. This week Oliver Kreylos, a researcher with the UC Davis W.M. Keck Center for Active Visualization in the Earth Sciences (KeckCAVES) and the UC Davis DataLab, shows us an alternative to looking at 3D data or models on a 2D screen: looking at them in full 3D through virtual reality! One problem in studying Earth’s dee ...[Read More]

Virtual Meetings: Hypnotic sedative or effective stimulant?

Virtual Meetings: Hypnotic sedative or effective stimulant?

Some people claim that teaching online courses or virtual workshops is not very different from face-to-face meetings. In my experience, however, it is much harder to sneak away secretly from a half-occupied seminar room than to withdraw from a virtual meeting where you simply mute the speaker to work on your emails located only one mouse click away. And that’s not all! In contrast to physically pr ...[Read More]

TS Must-Read – Wilson (1966) Did the Atlantic close and then re-open?

J.T. Wilson published “Did the Atlantic close and reopen?” in 1966, giving birth to the so called “Wilson Cycle”. The article is a key steppingstone for the theory of plate tectonics, and it is a must-read paper not only in tectonics studies but also in paleontology and stratigraphy. The questions raised can be generally abridged in two: “Why regions with similar fauna can be very far from each ot ...[Read More]

Natural Hazards 101: The concept of risk

Natural Hazards 101: The concept of risk

  In the first episode of the series of posts called Natural Hazards 101, we focused on the definition of hazard and natural hazard, considering the recent literature. In this episode, we wish to draw your attention to the concept of risk. Although a commonly used word, the term risk might mean different things to different people. What does risk represent, and what it means in the context of ...[Read More]

The Journey of an Antarctic Seismologist

The Journey of an Antarctic Seismologist

Thwaites Glacier is a massive region of the West Antarctic Ice Sheet on par with the size of Pennsylvania or the island of Britain and is over a mile thick in many places. It is currently retreating rapidly and is a likely candidate to contribute the most to rapid sea-level rise over the next few decades to a century. That’s the most important point there is to make. I’m part of a large internatio ...[Read More]

Lost in transl[ice]tion…

Three years have passed since sea-ice scientists from both climate modeling and remote sensing backgrounds met for an international workshop in Hamburg. The goal was to discuss how to further improve our understanding of sea ice and reduce uncertainties in climate models and observations (see this previous post). One suggestion was to work on observation operators. Let’s see what has happened in t ...[Read More]

The Sassy Scientist – sassy.disp(title = ‘geo-programming’);

With time to spare during self-isolation and local lockdown, Mark wonders: What programming language should I learn for my geoscience career? Dear Mark, The pandemic has made us look long and hard at our career choices. Were you inspired as a student by a cool field geologist in a documentary? Were you profoundly marked by that school trip at an active volcano? Did you fell in love with coral reef ...[Read More]
