Cascading events led to 2018 Kīlauea volcanic eruption, providing clues for forecasting
The 2018 eruption of Kīlauea Volcano was one of the largest volcanic events in Hawai'i in 200 years. This eruption was triggered by a relatively small and rapid change at the volcano after a decade-long build-up of pressure in the upper parts of the volcano, according to a recent study published in Nature Communications by earth scientists from the University of Hawai'i at Mānoa and U.S. Geological Survey. (2020-11-23)

Ancient zircon minerals from Mars reveal the elusive internal structure of the red planet
Analysis of an ancient meteorite from Mars suggests that the mineral zircon may be abundant on the surface of the red planet. By determining the age and hafnium isotope composition of these zircons, researchers from the University of Copenhagen have shown that a population of these crystals were sourced from the deep interior of Mars. If the researchers are correct, it means that the young zircons contain information about the deep, inaccessible interior of Mars, which provides insights into the internal structure of the planet.

(2020-11-17)

Crystals reveal the danger of sleeping volcanoes
Most active volcanoes on Earth are dormant and are normally not considered hazardous. A team of volcanologists from the University of Geneva has devised a technique that can predict their devastating potential. The scientists used zircon, a tiny crystal contained in volcanic rocks, to estimate the volume of magma that could be erupted once Nevado de Toluca volcano (Mexico) will wake up from its dormancy. Up to 350 km3 of magma are currently lying below. (2020-11-05)

Deep magma facilitates the movement of tectonic plates
A small amount of molten rock located under tectonic plates encourages them to move. This is what scientists from the LGL-TPE (CNRS/ENS de Lyon/UCBL1) have recently discovered. Their new model takes into account not only the velocity of seismic waves but also the way in which they are attenuated by the medium they pass through. The velocity of tectonic plates near the surface is thus directly correlated with the quantity of magma present. (2020-10-21)

Deep learning artificial intelligence keeps an eye on volcano movements
RADAR satellites can collect massive amounts of remote sensing data that can detect ground movements -- surface deformations -- at volcanoes in near real time. These ground movements could signal impending volcanic activity and unrest; however, clouds and other atmospheric and instrumental disturbances can introduce significant errors in those ground movement measurements. Now, Penn State researchers have used artificial intelligence (AI) to clear up that noise, drastically facilitating and improving near real-time observation of volcanic movements and the detection of volcanic activity and unrest. (2020-10-15)

A new chemical analysis upends conventional explanation for global cooling
Scientists have long known the earth cooled dramatically about 13,000 years ago, and the most likely explanation has been that it was caused by a massive object slamming into earth from space or bursting in the atmosphere. But now researchers have reported new evidence for another, more likely explanation - the eruption of a volcano on what is now the European continent, upending thinking about an event that shaped future evolution. (2020-07-31)

Scientists reveal an explosive secret hidden beneath seemingly trustworthy volcanoes
An international team of volcanologists working on remote islands in the Galápagos Archipelago has found that volcanoes which reliably produce small basaltic lava eruptions hide chemically diverse magmas in their underground plumbing systems - including some with the potential to generate explosive activity. These volcanoes might undergo unexpected changes to sudden such activity in the future. (2020-07-28)

COVID-19 lockdown caused 50% global reduction in human-linked Earth vibrations
