New research introduces the concept of Oceanic Mid-plate Superstructures (OMS) to describe large volcanic structures formed from various volcanic sources over time. The study focuses on the Melanesian Border Plateau (MBP), an example of an OMS, revealing its formation through four distinct volcanic episodes, combining hotspot activity and lithospheric movements, contributing to around 222 000 km² of intraplate volcanism.
A team of Earth scientists, meteorologists, geologists, and volcanologists has formulated a new theory explaining the phenomenon of volcanic fountaining. This breakthrough is based on the analysis of the 2021 Fagradalsfjall eruption in Iceland, as reported in the journal Nature Communications.
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 new study published in AGU’s Geochemistry, Geophysics, Geosystems has revealed the existence of a magma chamber beneath the Kolumbo volcano, located near Santorini, Greece. Using a high-resolution technology called full-waveform inversion, the study found that the magma chamber poses a serious hazard as it could produce a highly explosive, tsunamigenic eruption in the near future.
New research published in Nature Communications suggests the internal ‘plumbing’ system of the Stromboli volcano in Italy may have changed, allowing magma from deep beneath the surface to rise more easily, triggering violent and unpredictable blasts. The research follows a series of surprisingly strong eruptions and paroxysms in 2019.
A new analysis published in Science shows the eruption at Hunga Tonga–Hunga Haʻapai volcano in Tonga on January 15, 2022, created the highest volcanic plume ever recorded. This is the first time a volcanic plume has been seen to penetrate the stratopause.
A new study published in AGU’s JGR Solid Earth combined the petrological and geochemical data collected in recent decades at Campi Flegrei with numerical simulations, and placed new constraints on the source(s) of the current dynamics of the volcano. The study helps in defining the best monitoring strategies and forecasting a future eruption.
When the Hunga Tonga-Hunga Ha‘apai volcano in Tonga erupted on January 15, 2022, it sent atmospheric shock waves, sonic booms, and tsunami waves around the world. Now, new research published in Geophysical Research Letters shows the effects of the eruption also reached space, causing a major space weather event.
A catastrophic drop in atmospheric ozone layers 60 000 to 100 000 years ago likely contributed to a population bottleneck during that period. According to a new study, the event was triggered by the eruption of the Toba supervolcano in Sumatra, Indonesia. "Toba…
Researchers at NASA’s Jet Propulsion Laboratory in Southern California identified what triggers large-scale volcanic eruptions and the conditions that lead to them. Using data from the 2018 Kilauea eruption in Hawaii– its largest volcanic eruption in over 200…
