Why do Earth’s hidden stress fields matter for our future? Let’s explore the latest insights from the World Stress Map database

Asmae Ourkiya July 17, 2026

Beneath the serene landscapes we inhabit, the Earth’s crust is a battleground of constant, immense, and invisible tectonic forces. While humanity typically only notices this deep-seated stress when it violently releases in the form of an earthquake and volcanoes, these forces have always been shaping the structural bedrock of our planet. Understanding this hidden architecture is one of the most vi ...[Read More]

The theory of continental drift and how it changed the geosciences forever

Gillian D'Souza November 4, 2022

German scientist Alfred Wegener spent most of his life defending a shocking theory: that all the world’s continents were once part of the same land mass before they drifted away. For many years after he passed, his theory continued to be shunned, ridiculed, and labelled as pseudoscience. And then, several decades later, geologists began to find more and more proof to support his continental drift ...[Read More]

Imaggeo On Monday: Alps highest peak meets folded sea floor

Antoine Clausse August 23, 2021

During the late Jurassic, this dolostone was formerly at the sea floor, but after millions years of tectonic movements and natural forces, these rocks now appear at 3000m! Mont Blanc, the highest peak of the Alps is less than 20km away, and is visible in the background. Thank to the Alpine collision, this former sea floor was thrusted over gneiss and granite to make both geologists and mountaineer ...[Read More]

Imaggeo On Monday: Water Force

Daniela Lobianco May 31, 2021

A force is a push or pull upon an object resulting from the object’s interaction with another object. This image shows the most magnificent force in nature; water, interacting with an inclined rock formation, with a backdrop of the magnificent landscapes of Canada. Description by Daniela Lobianco, after the description on imaggeo.egu.eu. Imaggeo is the EGU’s online open access ...[Read More]

Imaggeo On Monday: Yardangs in the Gobi desert

Jonathan D. Müller May 24, 2021

Seeing the Yardang rock formations during sunset was a surreal experience. While they seem to have be standing in a sea of water that formed them, the fluid dynamics that actually lead to their existence is the result of wind abrasion by dust and sand and the removal of loose material by wind turbulence. The air flow and resulting pattern of erosion and the distribution of rocks determines their s ...[Read More]

Imaggeo On Monday: Tides at Young Sound

Maria Scheel May 10, 2021

The work of the autumn tides at Young Sound, Northeast Greenland, created a fine sand artwork just before the freezing in of the fjord with the approaching winter. Due to the changing sediment of the nearby Zackenberg river, the local coastal erosion is an object of great recent investigations. Description by Maria Scheel, after the description on imaggeo.egu.eu. Imaggeo is the EGU’s ...[Read More]
