Impact Factors have increased for all EGU journals in 2020!
  • EGU news
  • 1 July 2021

Newly announced journal metrics for EGU’s journals, managed by our publishing partner Copernicus, have revealed an increase in Impact Factor for all EGU Journals. Several journals, including Atmospheric Chemistry and Physics (ACP), Earth System Dynamics (ESD), Natural Hazards and Earth System Sciences (NHESS) and The Cryosphere (TC) have reached their highest value ever. See the full list of new details on Copernicus’ website.

Mapping the aerodynamic roughness of the Greenland Ice Sheet surface using ICESat-2: evaluation over the K-transect

We developed a method to estimate the aerodynamic properties of the Greenland Ice Sheet surface using either UAV or ICESat-2 elevation data. We show that this new method is able to reproduce the important spatiotemporal variability in surface aerodynamic roughness, measured by the field observations. The new maps of surface roughness can be used in atmospheric models to improve simulations of surface turbulent heat fluxes and therefore surface energy and mass balance over rough ice worldwide.


A discontinuous Galerkin finite-element model for fast channelized lava flows v1.0

Lava flows present a natural hazard to communities around volcanoes and are usually slow-moving (< 1-5 cm/s). Lava flows during the 2018 eruption of Kilauea volcano, Hawai’i, however, reached speeds as high as 11 m/s. To investigate these dynamics we develop a new lava flow computer model that incorporates a nonlinear expression for the fluid viscosity. Model results indicate that the lava flows at Site 8 of the eruption displayed shear thickening behavior due to the flow’s high bubble content.


Fracking bad language – hydraulic fracturing and earthquake risks

The potential for hydraulic fracturing (fracking) to induce seismicity is a topic of widespread interest. We find that terms used to describe induced seismicity are poorly defined and ambiguous and do not translate into everyday language. Such bad language has led to challenges in understanding, perceiving, and communicating risks around seismicity and fracking. Our findings and recommendations are relevant to other geoenergy topics that are potentially associated with induced seismicity.

“State of the ECS”: Proudly presenting the new commers!

Maria here! Well, it has been some time but now we have some exciting news! Our little ECS group is not that little anymore. After EGU five, yes I repeat, five new members joined our team! Yay. Without further ado, I give the floor to the newbies, so they can introduce themselves. Hi everyone! This is Angel! (Yes, it’s my real name!) I’m a geophysics PhD student at ETH Zurich studying core seismic phases with AlpArray. I have always enjoyed …


Imaggeo On Monday: An ever evolving landscape – Orog Nuur, Mongolia

At the transition from the Gobi Altay ranges to the Valley of the Lakes in South West Mongolia, the Ikh Bogd mountain towers almost 3000 m above the aridifying endorheic Orog Nuur Basin. The actively deforming mountain front shows traces of multiple earthquakes, which in turn affect the alluvial sediments deposited in the basin. Simultaneously, strong south-eastward winds create beautiful barchan dunes. This photo reflects the interplay of multiple dynamic factors that shape and influence the landscape system. Description by …


Meet and greet with the Natural hazards Early career scientists Team – NhET

Do you know that there is a Natural Hazards team of clever, fun and friendly early career scientists? This team takes care of the blog you are reading (and we hope enjoying) and organises and helps with sessions, short courses and great debates during the EGU General Assembly. Moreover, we created a network of early to mid-career scientists from different disciplines and backgrounds of the Natural Hazards that serves as support and contact point. Do you need someone with skills …
