For the first time in 2006 Cannat and co-workers described a smooth seafloor type in the mid-ocean ridge located in the SW Indian Ocean (SWIR). The 660-km-long off-axis bathymetry, gravity, and magnetic dataset presented in the study lies near the Rodrigues triple junction (RTJ in Fig. 1). The must read paper expanded the previous conceptual models that considered mid ocean ridges as primarily vol ...[Read More]

Geodesy Division Year In Review 2022
Hi EGU Community! With the first blog post of 2023, we want to look back at what happened in the G Division during the last year and give an outlook on what you can expect for the new year! Looking back on 2022 G Division at the General Assembly After two years of online-only general assemblies (GAs), in 2022 the GA switched to a hybrid format with an in-person part in Vienna and online participa ...[Read More]

COVID-19 and natural hazards: a complex multi-risk scenario
COVID-19 has been a disruptive ‘tsunami’ that most countries were not prepared to handle. The pandemic has been representing a global slow-onset long-lasting disaster that has drastically challenged all emergency management systems worldwide. The pandemic slow-onset disaster has been characterized by a prolonged emergency phase with varying intensity levels, and a cyclic behavior, where the interp ...[Read More]

On the Frontline of the Mission for Marsquakes
This week we interview Géraldine Zenhäusern, a PhD student at ETH Zurich’s Department of Earth Sciences, about her experience of being on the frontline of spotting Marsquakes with NASA’s InSight mission…. What is the InSight mission? The NASA InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission is a geophysical observatory (see Fig. 1) which landed ...[Read More]

Meet the Early Career Scientists team of our division!
Hi, this is your ST-ECS team. We are a group of Early Career Scientists (ECSs) of the Solar-Terrestrial (ST) division, and we enjoy organizing events and activities with and for ST-ECS, both during the EGU General Assembly and throughout the year. Our aim is to increase the visibility of ECSs and provide you with opportunities for networking. Currently the team is formed by: Dr. Maxime Grandin Max ...[Read More]

Did you know that thawing permafrost is impacting Arctic livelihoods already today?
Would you like to join me on a little trip up North today? We will be visiting a small community in the Canadian high Arctic – a community built on permafrost ground. This sounds pretty cool in the first place, but brings along quite a few challenges that most of us probably do not have to think about. Let me introduce you to Tuktoyaktuk, the community that is endangered to fall into the sea ...[Read More]

The importance of our SSS (…Soil Support Staff!) #10
We are looking forward to celebrating another excellent exhibition of soil science at this year’s EGU General Assembly. Of course, very little soils research could take place without the work carried out by technicians, laboratory assistants, and research support staff. This monthly blog post is our opportunity to thank these key individuals, and their tireless efforts to maintain our labora ...[Read More]

Outcrop analogues to Carbon Sequestration Targets: the Gog Quartzite of Alberta – including a short virtual field trip!
Introduction In 2022 I was asked to put together a virtual field trip looking at carbon sequestration (CCS). We are particularly lucky in Alberta in having three excellent Cambrian targets for CCS including the Basal Cambrian Sandstone, currently being used for CCS in Shell’s QUEST project, quartzites of the Deadwood Formation (being utilized for a CCS project in Saskatchewan) and the Gog Quartzit ...[Read More]

Arc and Intraplate Volcanism in Northeast Asia Since mid-Miocene: Numerical model studies
Northeast Asia may be one of the best natural laboratories to investigate both arc and intraplate volcanisms which have developed since the mid-Miocene. The arc volcanoes have occurred above the sinking young (Philippine) and old (Pacific) oceanic plates in Southwest and Northeast Japan subduction zones, respectively. The intraplate volcanoes across the Korean Peninsula and China have occurred abo ...[Read More]

Seismic Swarms in the Azores
Will Sturgeon – Post-Doc at the Earth Sciences Department of University College London, UK – takes us on a journey to the Azores to deploy seismometers in response to the seismic swarm earlier in 2022… Protruding from the central Atlantic Ocean, about 1,400 km west of Lisbon, is an archipelago of nine volcanic islands, known as the Azores. Also described as “Europe’s Hawaii”, the ...[Read More]
