Paper focus: Plumbing the depths of magma crystallization by Hugo Moreira and co-authors

Paper focus: Plumbing the depths of magma crystallization by Hugo Moreira and co-authors

Do you know when you stumble upon a very interesting paper, with a captivating title and you wish you could talk to the author(s)? Well, I did just that. It happens that I know the first author quite well, so I had no shame in contacting him and ask about it. One of his latest papers was published in Geology with the title “Plumbing the depths of magma crystallization using 176Lu/177Hf in zi ...[Read More]

The Legend of Zelda: A Link to Learning Hydrology?

The Legend of Zelda: A Link to Learning Hydrology?

Can we learn about hydrology through video games? Plenty of educational video games exist specifically to teach scientific concepts, but lots of these games are not particularly fun. But can popular commercial-off-the-shelf (COTS) video games fulfill the same function of teaching players scientific concepts through tangential learning as a secondary benefit to enjoying the game? Existing peer revi ...[Read More]

Earthquake Watch: The 6 February 2023 Kahramanmaraş Earthquakes – A catastrophic day for Turkey

Earthquake Watch: The 6 February 2023 Kahramanmaraş Earthquakes – A catastrophic day for Turkey

Assoc. Prof. Dr Onur Tan from Istanbul University-Cerrahpasa outlines the 6 February 2023 Kahramanmaraş Earthquakes for the Earthquake Watch. February 6, 2023, was a catastrophic day for Turkey. The most destructive earthquake in the last century, Mw 7.8, hit the eastern part of the country at 04:17 local time. Unexpectedly, the second Mw 7.5 mainshock shook the region nine hours later. The mainsh ...[Read More]

Geodetic Data and Products – Idea of a Central Access Point

  The services of the International Association of Geodesy (IAG) provide very important and valuable geodetic data, information, and data products that are increasingly relevant for Earth System research, including monitoring of global change phenomena and a wide range of diverse applications such as satellite navigation, surveying, mapping, engineering, geospatial information systems, and so ...[Read More]

Tropical conditions in southern Germany: Investigating the sedimentation of Middle Jurassic shallow marine environments in the South German Basin by cyclostratigraphy

Tropical conditions in southern Germany: Investigating the sedimentation of Middle Jurassic shallow marine environments in the South German Basin by cyclostratigraphy

Most people would not relate Central Europe to a tropical environment today. During the Middle Jurassic (174-163 Ma ago), however, such conditions prevailed in most parts of the nowadays  landmass that was almost completely covered by a shallow epicontinental sea (estimated 0-100 m water depth) except for several emerged areas and islands. During this time, the continent of Pangaea broke apart, as ...[Read More]

Highlighted Paper – The ice factories of the Arctic Ocean

Highlighted Paper – The ice factories of the Arctic Ocean

Each year, the Arctic sea ice goes through a cycle of melting and freezing. From March to September, sea ice gradually melts and becomes thinner, and from October to March, the water freezes again. In our warming climate, we see that more and more ice melts each year. One would expect that the ice would also freeze less, but we have observed that the ice growth – or ice production – has increased ...[Read More]

How does slab tearing evolve?

How does slab tearing evolve?

Slab tearing refers to the gradual propagation of the break-off of a subducting plate. As observed in numerous modern and ancient convergent tectonic settings, the growth of the tear “window” in the downgoing plate has strongly influenced various geologic and geodynamic processes, such as depocenter migration of foreland basins, uplift rates in mountain ranges, earthquakes, volcanism, and flow pat ...[Read More]

New spheres of scientific publishing

New spheres of scientific publishing

Many of you have noticed that EGUsphere went online, the new preprint repository hosted by EGU, as a service for the entire geosciences community. This repository can be used by any geoscientist to deposit their preprint even those that are not submitted to Copernicus journals. If you submit a preprint, your manuscript will receive a DOI number,  the EGUsphere logo and – most importantly – a discu ...[Read More]

Connecting the dots: the importance of recognising multi-hazard events in disaster reporting

Connecting the dots: the importance of recognising multi-hazard events in disaster reporting

In the past year, the world has witnessed many severe disasters caused by multiple hazards whose impacts overlapped in time and space. February this year, two severe earthquakes hit Syria and Turkey shortly after each other, followed by two more powerful earthquakes and over a hundred aftershocks in subsequent weeks [1,2]. The disaster caused over 48 thousand fatalities, and many people are still ...[Read More]
