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.

Swarm mission discovers interannual waves in Earth’s core

Swarm mission discovers interannual waves in Earth’s core

Using information from ESA’s Swarm satellite mission, scientists have discovered a completely new type of magnetic wave that sweeps across the outermost part of Earth’s outer core every seven years. The discovery offers a way to probe the cylindrical radial component of the magnetic field inside Earth’s core.

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.
