Study reveals magma chamber at submarine Kolumbo volcano near Santorini, Greece poses a serious threat

Study reveals magma chamber at submarine Kolumbo volcano near Santorini, Greece poses a serious threat

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 era of violent and unpredictable eruptions at Stromboli volcano, Italy

New era of violent and unpredictable eruptions at Stromboli volcano, Italy

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.

Magmatic degassing in Campi Flegrei in recent bradyseismic crises, Italy

Magmatic degassing in Campi Flegrei in recent bradyseismic crises, Italy

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.

Hunga Tonga-Hunga Ha’apai eruption caused a major space weather event

Hunga Tonga-Hunga Ha’apai eruption caused a major space weather event

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.

Caldera collapse triggers large-scale volcanic eruptions

Caldera collapse triggers large-scale volcanic eruptions

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…

Research offers new clues about where and how subduction starts on Earth

Research offers new clues about where and how subduction starts on Earth

An international team of researchers published a new study providing new clues about how and where subduction begins on Earth, the process behind the deadliest volcanic eruptions. The Earth's largest earthquakes and most explosive volcanoes occur at subduction…

Geysers may be signaling magma intrusion under Yellowstone caldera

Geysers may be signaling magma intrusion under Yellowstone caldera

Steamboat Geyser in Wyoming is the world's tallest active geyser, which sometimes blasts water over 90 m (300 feet) into the air. At times, the geyser stays quiet for years then abruptly bursts back to life– a behavior that has been puzzling scientists. A new…
