In Gobustan, Azerbaïdjan, gases such as methane or carbon dioxide are emitted in the underground. They lower the density of the overlying sediments which are pushed upwards by buoyancy. Fingering instabilities occur, where more mobile and lighter sediments form vents and mud volcanoes with upwards moving material. Many small scale cones are deposited when the …[Read More]
Hi Morelia. Thank you for joining us today! Could you tell our readers a bit about yourself and your research? Hi, I am Junior Professor for Marine Geomechanics at GEOMAR Helmholtz Centre for Ocean Research Kiel and Kiel University in Germany. I graduated at the University of Bremen (Germany) and did my PhD in 2013 …[Read More]
Scientists have combed through the mysteries offered by this ridge for a long time. This is an aerial image of the linear north-south ridge in South-Eastern Utah. First mapped by modern geoscientists in the late 19th century, the ridge is home to numerous Puebloan cliff dwellings and petroglyphs. It is a National Natural landmark and …[Read More]
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 …[Read More]
This picture was taken from the N.B. Palmer ice breaker during the PIPERS expedition in the austral winter of 2017. Two researchers and a marine technician were drilling cores in the sea ice of the Ross Sea. The ice was too thin and started to crack (see the fault in the background), so the team …[Read More]
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we put the journals that publish science from those Divisions at the top of the Highlights roundup. For October, the Divisions we are featuring are: Natural Hazards (NH), Seismology (SM) and Geochemistry, Mineralogy, Petrology and Volcanology (GMPV). They are served by the journals: …[Read More]
“If you see me, then weep” Like the foreboding inscription witnessed by Dante as he passed through the gates of Hell, the inscription chiselled into the so-called “hunger stone” marks the passing of a threshold into suffering. As the hunger stone emerges from the dwindling waters of the Elbe River, Czechia, it reveals a history …[Read More]
Around the world, the month of October is observed as Black History Month and includes the International Day for Disaster Reduction. While both these observances are significant in their own right, it gave EGU the opportunity to hear from geoscientists of Black, Indigenous, and People of Colour (BIPOC) communities about the many ways that race …[Read More]
The drying out of the soil leads to the hazard of flash floods in the wadis of the Dead Sea Valley during sparse but strong rain events. During longer precipitation-free periods and extreme low relative humidity, driven by mesoscale wind, the soil crust ultimately tends to break into piece.

Communicating with the public and policymakers enables scientists to share their passion with those outside of their field and create greater impact. Often when scientists consider engaging non-experts, they imagine public lectures or blog posts, but finding more creative ways to communicate scientific information can be both rewarding and incredibly effective. This month’s GeoPolicy Blog …[Read More]
