Haakon Fossen and Geane Carolina G. Cavalcante published their seminal review on the topic of shear zones in 2017 in the journal Earth-Science Reviews. The work summarizes the scientific findings on the development and quantification of ductile shear zones sincefrom the the 1960s up to recently. It describes the fundamental aspects of the initiation and growth of shear zones across scales. First, ...[Read More]
For many of you September means back to school, for us September means the return of the blog. Behind the scene this summer, the bright new editorial team prepared fresh blog posts to share with the community. We are very excited to welcome the new editors, happy to start their blog adventure. The 2025-2026 team is a group of early career scientists editors from diverse backgrounds, continents and ...[Read More]
Queer Quarterly is the blog series of the EGU pride group, a LGBTQIA+ team of geoscientists engaged to uphold and improve the rights of the community in the EGU organization. This week’s post is dedicated to allyship: how people outside of the community can support our efforts. The term LGBTQIA+ is the abbreviation for Lesbian, Gay, Bisexual, Transgender, Queer, Intersex, and Asexual. The addition ...[Read More]
Earthquakes shake the Earth almost every day, but what exactly happens within rocks during these seismic events is a matter of debate in the scientific community. The article “Do faults preserve a record of seismic slip: A second opinion,” published in 2015, offers a thoughtful review of the sure and potential records of seismic slip in rocks. The paper examines the notion that rocks i ...[Read More]
The worldwide relatively frequent recurrence of volcanic eruptions, earthquakes and tsunamis, as well as their strong impact on society make them the most common sources of myths. The most intriguing part is how different cultures describe relatively similar events in very different ways. Among them, the myths at the base of the origins of the Crater Lake in Oregon (USA), mainly orally inherited f ...[Read More]
In this Must Read paper “3D seismic analysis of the structure and evolution of a salt-influenced normal fault zone: a test of competing fault growth models (2013)”, by Christopher A-L. Jackson and Atle Rotevatn used detailed 3D seismic reflection data from the Suez Rift, Egypt, to gain a better understanding of the structural evolution of normal faults. Specifically, the paper shows th ...[Read More]
As readers of this blog know, geology is an awe-inspiring subject, dealing as it does with immensely powerful forces operating on time scales, pressures, and temperatures we can barely fathom. It is geological processes that are responsible for the continents, oceans, mountain ranges, indeed for all the landscapes we see around us. Even though many of these processes operate over deep time and dee ...[Read More]
This edition of ‘Features from the field’ is brought to you by Faris Beg, a masters student on the EU Erasmus Mundus Joint Master’s program in planetary geosciences—GeoPlaNet. This blog is a result of a geological field excursion carried out collectively in groups by students, organized by the GeoPlaNet consortium in Alcañiz, Spain. He will be talking about his observations and l ...[Read More]
Rifted margins are regions at the transition from oceanic to continental crust, formed by the stretching and thinning of the Earth’s lithosphere before the creation of new ocean basins. The study focused on three key transects across Atlantic rifted margins. In their 2013 article in Marine and Petroleum Geology, Peron-Pinvidic et al. present a comparative analysis of the architecture of vari ...[Read More]
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 re ...[Read More]
