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.

The fullest investigation of the massive Hunga Tonga-Hunga Ha’apai eruption to date

The fullest investigation of the massive Hunga Tonga-Hunga Ha’apai eruption to date

In January 2022, Hunga-Tonga Hunga-Ha’apai (HT-HH) emitted the biggest atmospheric explosion recorded on Earth in more than 100 years. Several months after the eruption, a New Zealand-led team has completed the fullest investigation to date into the eruption of this underwater Tongan volcano.

Study shows how Earth-Sun distance dramatically influences annual weather cycles in the equatorial Pacific in a 22 000-year cycle

Study shows how Earth-Sun distance dramatically influences annual weather cycles in the equatorial Pacific in a 22 000-year cycle

A new research led by the University of California, Berkeley, demonstrates that one driver of annual weather cycles in the eastern equatorial Pacific Ocean—in particular, a cold tongue of surface waters stretching westward along the equator from the coast of South America—has gone unrecognized: the changing distance between Earth and the Sun.

Reactivation of dormant Edgecumbe volcano, Alaska

Reactivation of dormant Edgecumbe volcano, Alaska

Researchers reporting in AGU’s Geophysical Research Letters show that the seismic swarm detected near Mt. Edgecumbe volcano in Southeast Alaska, U.S. in April 2022 was caused by magmatic activity taking place under this transform fault volcano previously considered dormant.

Lava field in Lanzarote twice as thick as previously thought, Canary Islands

Lava field in Lanzarote twice as thick as previously thought, Canary Islands

An international group of researchers reporting in AGU’s Geochemistry, Geophysics, Geosystems used radar satellites to measure how fast parts of the lava fields in Lanzarote, Canary Islands are sinking nearly three centuries after a massive eruption that lasted from 1730 – 1736.
