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.
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.
A new analysis published in Science shows the eruption at Hunga Tonga–Hunga Haʻapai volcano in Tonga on January 15, 2022, created the highest volcanic plume ever recorded. This is the first time a volcanic plume has been seen to penetrate the stratopause.
An international team of scientists reporting in The Astronomical Journal discovered a large Apollo-type near-Earth object (NEO) hiding in the Sun’s glare.
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.
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.
Researchers reporting in AGU’s JGR Solid Earth identified changes in the magnetic field near intermediate-large earthquakes in California in the days before the earthquakes happened, providing evidence that there is a physical change that can be observed in the days before an earthquake.
Scientists from the University of Iceland, the Icelandic Met Office and their colleagues have published two papers in the latest issue of Nature presenting new findings from the 2021 eruption at Fagradalsfjall – the first eruption on the Reykjanes Peninsula after 800 years of dormancy.
A new study published recently in Remote Sensing proposes the implementation of machine learning support vector machine (SVM) technique, applied with GPS ionospheric total electron content (TEC) pre-processed time series estimations, to evaluate potential precursors caused by earthquakes.
A project investigating the effect of solar storms on railway signals, presented this week at the National Astronomy Meeting (NAM 2022) by Cameron Patterson, a PhD student at Lancaster University, shows how fluctuations in space weather are disrupting train signals and causing significant delays.
