On a late afternoon in Colorado’s Great Sand Dunes, the sun came out from behind the clouds for a brief moment before it went behind the horizon, illuminating the stoss side of an eroding dune. Sand originated from lacustrine deposits in the San Luis Valley; the Sangre de Cristo mountains, which can be seen in the background, provided a source of some of the sand. This image therefore illust ...[Read More]
This year marks the 100th anniversary of Milutin Milankovitch’s first paper about Earth’s climate. Milankovitch argued that the amount of solar radiation Earth receives, and hence its climate, varies cyclically as its orbit changes due to gravitational tugs from the other planets. His climate theory fell into disrepute during the 1950’s but was rehabilitated in the 1970’s. Today, many peopl ...[Read More]
This image shows bottomset beds from the Kerinitis Gilbert-type delta. The Pleistocene delta uplifts along the active southern margin of the Corinth rift in Greece. A bottomset bed is one where layers of sedimentary material lying along the bottom of a body of water near the point of entry of a stream are subsequently covered by foreset and topset beds in the formation of a delta. Thus in this ima ...[Read More]
Earlier this year, the EGU hosted the Integrating science into the EU Green Deal event in collaboration with the Intergroup on Climate Change, Biodiversity and Sustainable Development to outline how the geosciences can most effectively support the European Green Deal and ensure its ambitious biodiversity and zero-pollution targets are reached. The event provided policymakers, scientists and indust ...[Read More]
This image shows benthic foraminifera species of Favulina hexagona (Williamson, 1848) together with nanofossils enclosed inside the shell hexagons. This modern foraminifera species was found in the sediment core retrieved from the western slope of the Rio Grande Rise (western South Atlantic). Description by Liubov Kuleshova, after the description on imaggeo.egu.eu. Imaggeo is the EGU ...[Read More]
Diplono Petris near Agios Pavlos in the south of Crete island is one of Europe’s most impressive folded rock formations. The rock strata document an alternation of different limestone layers in the pindos top of the Cretan ceiling pile. These sediments, once deposited in a deeper ocean basin of the Pindos Ocean, were deformed in the course of Alpine fold tectonics, triggered by the Northern ...[Read More]
A Natural Hazards Earth System Sciences (NHESS) paper proposes a new sampling method for reducing uncertainty in geographical location in seismic hazard risk analysis, with implications for the insurance industry and risk communication in general. Globally, rapid urbanisation is increasing the risk of exposure of human populations and infrastructure to natural hazards, including earthquakes ...[Read More]
This picture shows several trees and the sky reflecting in floodwater during an event that occured in February 2019 in front of the famous Postojna cave (Slovenia). In Slovenian karst areas, floods are considered as a very common natural phenomenon that can occur several times per year. While most of them are not harmful for local people, the most severe events cause considerable damages and might ...[Read More]
A series of deadly landslides and debris flows occurred in March 2013 in Petropolis, a municipality in the Brazilian state of Rio de Janeiro. This photo has been shot a little more than a month later. It highlights the important “supporting role” played by sewer pipes in this disaster. Description by Michele Calvello, after the description on imaggeo.egu.eu. Imaggeo is the EGU’s ...[Read More]
After telling a personal and traumatizing field experience to my fellow colleagues of color, I found that we all had shared similar events! Shocked and outraged, I wanted to find a place to expose and highlight these events thus the #BlackInTheMud panel was created. This event was inspired by this picture. And it’s so funny because this photo has been used, until it’s almost like a stock photo on ...[Read More]
