The Italian Space Agency (ASI) announced the discovery of a rare meteorite containing aluminum-copper alloy quasicrystals in Mount Gariglione, Calabria, marking a significant advancement in planetary sciences.
A new study published in Science Advances by René M. Van Westen, Michael Kliphuis, and Henk A. Dijkstra on February 9, 2024, unveils a physics-based early warning signal indicating the Atlantic Meridional Overturning Circulation (AMOC) is on a tipping course towards collapse.
Researchers from Penn State and Brown University have uncovered how rocks from ancient subduction zones can forecast tectonic behaviors between significant earthquakes, enhancing our ability to predict such natural disasters.
A group of geoscientists have recently challenged the conventional understanding of continental formation by presenting evidence that the origins of continents can be explained by internal geological forces alone, without initiating plate tectonics. The study highlights the role of oceanic plateaus in the early Earth’s crustal development.
A new study led by the University of St Andrews, in collaboration with international researchers, reveals that historical volcanic eruptions, particularly in high latitude regions, have caused significant yet transient global cooling effects. Published in the Proceedings of the National Academy of Sciences, the research utilized sulfur isotopes from ice cores to trace the climatic impact of volcanic eruptions in the Northern Hemisphere, particularly during notably cold decades like the 540s, 1450s, and 1600s.
A recent study published in Scientific Reports discovered volcanic debris from the Taupō eruption approximately 1 800 years ago deeply embedded in Antarctic ice. The findings, made at a depth of 279 m in West Antarctica, offer a precise date for the historical New Zealand eruption.
