By analyzing lava samples, researchers show how chemical processes that occur during magma’s ascent to the surface may contribute to a volcano’s eruptible state.
Una vez que una erupción volcánica masiva termina, el sistema subyacente puede mantenerse activo por miles de años. Una nueva investigación vislumbra cómo funcionan los ciclos de super erupciones.
Tree core chemistry can explain what happened before Mount Etna’s 2002 eruption and suggests that trees could play a role in rebuilding past eruptions.
Once a massive volcanic eruption is finished, the underlying system can remain active for thousands of years. New research illuminates how supereruption cycles work.
New research indicates the cooling effect of rare, large eruptions will increase, whereas the effects of more frequent, smaller eruptions will be reduced.
A strategy that combines geologic mapping with data on how the planet’s surface emits and absorbs microwave radiation could potentially identify recent lava flows.
Pressure from both magma and gas can trigger eruptions. Monitoring degassing can help predict eruptions but only if the magma system is well understood first.
Volcanologists have historically focused on the risks of large-scale eruptions, but new research highlights how small eruptions can combine with human-made vulnerabilities to cause catastrophic impacts.
NASA’s rapid response plan for gathering atmospheric data amid major volcanic eruptions, paired with efforts to improve eruption simulations, will offer better views of these events’ global effects.
Last year, a new collaborative initiative conducted a hypothetical volcano response exercise. A month later, they put the knowledge gained to use during an actual eruption.
