Seismology, volcanoes, crust of earth

Until recently, ocean margins were the only part of the seafloor that was of interest to Earth system research – or those places where new seafloor is created, i.e., the mid-ocean ridges. In theory, though, very little happens in the oceanic crust except at these ridges. But new findings from...

The eruption of the underwater volcano Hunga Tonga in 2022 was the most explosive eruption of the past decades. Dr. Ákos Horváth used geostationary satellite imagery with a time resolution of  1 minute to characterize the generated atmospheric waves more accurately than previous studies. The...

Like a very, very low note: Seismologists have been puzzling over vibrations originating beneath the sea in the Gulf of Guinea since the 1960s. The signal can even be picked up all over the world. Dr. Charlotte Bruland and Prof. Céline Hadziioannou have embarked on a study in search of clues...

Santorini is a picturesque archipelago in the southern Aegean. The islands encircle a massive volcanic caldera, which the ocean has long-since covered over. Some speculate that Santorini is all that’s left of Atlantis – the fabled, highly advanced island empire that suddenly vanished. The fact...

In order to limit global warming, in the future greenhouse gases will have to be removed from the atmosphere – it’s the only way to achieve climate targets. One way of doing so would be to permanently store carbon dioxide underground. However, geophysicist Prof. Christian Hübscher has...
