TS Must-Read – Wang et al. (2012) Deformation cycles of subduction earthquakes in a viscoelastic Earth

Large subduction earthquakes cause perturbation of the subduction system, whose response depends on its rheological characteristics. The evolution of the subduction system from earthquake to earthquake is defined as subduction earthquake cycle (SEC), and is characterised by three main processes that operate over decades/centuries: postseismic afterslip, viscoelastic mantle relaxation, and fault relocking. Despite the precise …[Read More]

Do-It-Yourself (DIY) in Geoscience Miniseries – Part 3: Getting it all together – Cables, Breadboards and Circuit Boards

You got all your components for your project, so now it’s all about getting it all together. Then it’s great to be able to quickly exchange components and change wiring. That’s where a so-called “breadboard” comes in handy. It’s an easy to use device where you can connect microelectronic components without the need to solder …[Read More]

Linking the Earth’s Engine and Landscape Formation and Evolution

The Earth’s internal engine drives several geodynamic processes such as continental rifting and dynamic topography, shaping mesmerizing landscapes. Through numerical modeling, insights into formations like the Continental Rift of Southeastern Brazil deepen our appreciation of Earth’s dynamic nature and the forces sculpting its surface. The heat engine beneath our feet Not so long ago, human …[Read More]

Using rainy day temperatures to predict the future of 100-year downpours

Using rainy day temperatures to predict the future of 100-year downpours

It’s hard to overstate the importance of so-called “rainfall frequency analysis,” or the estimation of rare rainfall probabilities such as the 100-year storm. Billions of euros worth of infrastructure and planning decisions are made every year around the world based on such statistics.  Unfortunately, extreme short-duration rainfall—meaning very high rainfall rates over a few minutes …[Read More]

Modelling the heat mitigation effects of blue roofs and green roofs to assess climate change adaptation potentials in dense urban environments

Urban areas often show higher temperatures than their surrounding rural areas, especially during heat events. This phenomenon is called the Urban Heat Island (UHI) effect. The magnitude of the UHI effect is expressed by the absolute temperature difference between the rural and the urban area and can reach more than 10 °C. During past decades, …[Read More]

Exploring rheology of Earth’s materials: The marvels of high-temperature high-pressure deformation experiments

The Earth, with its towering mountains, shifting tectonic plates, and dynamic geological processes, has always been a subject of fascination and inquiry for scientists. Amidst the vast array of scientific disciplines, one relatively small yet impactful field, known as experimental rock deformation, plays a crucial role in unraveling the mysteries hidden beneath the Earth’s surface. …[Read More]
