Application of lubrication theory in understanding subduction interface dynamics
Plate interface lubrication is essential for stabilization and continuation of subduction process for million of years. The magnitude of plate interface lubrication determines transfer of stress between two converging plates, topography of mountain belts, transportation of volatiles to the mantle, and return flow of high to ultra-high pressure rocks to the earth’s surface. In this …[Read More]
Global seismoacoustic waves from the Hunga eruption (Tonga)
Jelle Assink, Senior Geophysicist at KNMI, takes us through the details of the various kinds of waves produced by the Hunga eruption in Tonga earlier this year… On January 15, 2022, a powerful volcanic eruption occurred in the Tonga archipelago in the Pacific Ocean when the submarine Hunga volcano exploded around 04:15 (UTC). This explosion …[Read More]
The Cryosphere meets the Twittersphere
Twitter is a place that can be full of an overwhelming amount of information, and often it becomes difficult to hear about new information amongst the noise of all the tweeting. To help our fellow cryo-enthusiasts learn more about equality, diversity and accessibility within the cryosphere, we’re highlighting a few twitter accounts that we think …[Read More]
Did you know… that glaciers can sing?
Have you ever wondered what the voice of a glacier sounds like? Well, listen here! And if you want to know how the glacier makes these sounds, then let’s take a walk on the ice side… Close your eyes and think of the time you were in the middle of the mountains. On a snow …[Read More]
Reflection after the investigation of the direct First Parker Solar Probe Observation of the Interaction of Two Successive ICMEs
In Heliophysics there is a scarcity of in-situ buoys that allows us to monitor and track the solar wind changes in our Sun’s atmosphere, the heliosphere. NASA’s Parker Solar Probe (PSP) mission is one of those buoys that, together with Solar Orbiter (SolO, ESA/NASA Collaboration), is bringing a breath of fresh air in the effort …[Read More]
Resolving the very fine details of the Sun in low frequency radio
The Sun is an active radio emitter, it produces radio emissions in a wide frequency range from kHz to THz. The solar atmosphere has a complex distribution of magnetic field, plasma density, and temperature. These different properties of the solar atmosphere will result in different radio emission features at different frequencies. In principle, the plasma …[Read More]
EGU22: What makes a good CV?
This year for EGU22 we wanted to make participation in the Jobs and Careers events equally accesible whether you are participating remotely or on-site, so we added the ‘Ask me for my CV’ sticker that you can put in your profile to let people know that your CV is available. But what about the actual …[Read More]

Ice-hot news: A cryo-summary of the new IPCC assessment report!
We have waited eight years for it, and it is finally out: the 6th Assessment Report of the Intergovernmental Panel on Climate Change (a.k.a. « IPCC AR6 »)! And it is more than 10,000 pages long across Working Groups! Fortunately, a synthesis report integrating the findings of all three working groups should be released in …[Read More]
