  Across the Arctic lies evidence for a massive past volcanic event, called the High Arctic Large Igneous Province (HALIP). This ancient volcanic event is particularly unusual in that it appears to have lasted for over 50 million years. Could a single deep-seated mantle plume cause such wide-spread and long-lived volcanism? In a recent study published in the journal G-cubed (Heyn et al., 2024 ...[Read More]

Geodynamicists often try to answer scientific questions related to the Earth interior, but direct observations of such depths are rather limited–unless you are character in a Jules Verne’s novel or a prominent scientist in the movie The Core–. A way to deal with this issue is to rely on indirect methods, with seismic tomography being one of the most widely used by geoscientists. Howeve ...[Read More]

One of the best-researched and preserved impact craters on Earth is the Ries Crater (Germany). Hikers, bikers, school groups,  and geo-tourists from all over the world come here in search for the evidence of the cosmic catastrophe. In this week’s blog post, PhD student Katherine Villavicencio from University G. d’Annunzio (Italy) shares her experience when attending the Summer School “Impacts and ...[Read More]
