Sichuan Province earthquake offers lessons for landslide prediction from GNSS observations
Using data collected from a 2022 magnitude 6.8 earthquake in Luding County in China's Sichuan Province, researchers have tested whether Global Navigation Satellite System (GNSS) observations could be used for rapid prediction of earthquake-triggered.....»»
Water delivered to the mantle by aluminum enriched hydrated slabs?
Dense hydrous magnesium silicates (DHMSs) are generally considered as primary water carriers from the shallow lithosphere to the deep mantle transition region (MTR; 410–660 km in depth). Among DHMSs, Superhydrous phase B (hereafter, SuB) holds the.....»»
Mass extinction 66 million years ago triggered rapid evolution of bird genomes, study finds
Shortly after an asteroid slammed into Earth 66 million years ago, life for non-avian dinosaurs ended, but the evolutionary story for the early ancestors of birds began......»»
Researchers explore the potential of clean energy markets as a hedging tool
Climate change has significantly impacted lives worldwide and prompted governments to adopt policies promoting sustainability and use of clean energy sources. This shift to clean energy has triggered increased investments in renewable energy and tech.....»»
Solar storms could cause more auroras on Tuesday night
Massive explosions on the sun have triggered warnings of geomagnetic storms that could create dazzling auroras in the northern United States, Europe and southern Australia on Tuesday night......»»
Some good may come out of the CrowdStrike outage
Estimated financial losses due to the recent massive IT outage triggered by the faulty CrowdStrike update are counted in billions, but the unfortunate incident is having several positive effects, as well. Some silver linings As CrowdStrike was forced.....»»
Week in review: CrowdStrike-triggered outage insights, recovery, and measuring cybersecurity ROI
Here’s an overview of some of last week’s most interesting news, articles, interviews and videos: Microsoft releases tool to speed up recovery of systems borked by CrowdStrike update By now, most people are aware of – or have been personally af.....»»
New study supports stable mantle chemistry dating back to Earth"s early geologic history
A new analysis of rocks thought to be at least 2.5 billion years old by researchers at the Smithsonian's National Museum of Natural History helps clarify the chemical history of Earth's mantle—the geologic layer beneath the planet's crust......»»
Study reveals historical mismatch in Southern Ocean contributes to heat and carbon uptake
The Southern Ocean plays a central role in the global uptake of heat and carbon, which is widely thought to be due to its unique upwelling and circulation. An international research team, led by the University of Liverpool, explored whether there are.....»»
Lethal bird flu could decimate Oceania"s birds—from vigilance to vaccines, here"s what Australia is doing to prepare
Avian influenza viruses have infected the world's birds for millennia. We first became aware of them in the 19th century, when mass deaths of poultry triggered interest in what was then called "fowl plague.".....»»
Update: Worldwide IT outage due to buggy Crowdstrike sensor configuration update
The world is 16+ hours into what looks like the biggest IT outage in history, triggered by a defective update for Crowdstrike endpoint security software for Windows machines. The price of both Crowdstrike’s and Microsoft’s shares has tumb.....»»

How mantle hydration changes over the lifetime of a subduction zone
Because of interactions with Earth's hot mantle, water-logged oceanic plates release water as they slide beneath less dense overriding plates in subduction zones. This water rises and hydrates the mantle above it, contributing to the formation of vol.....»»

Grain boundaries weaken in planetary interiors, research suggests
Mantle convection and associated plate tectonics of planets like the Earth are governed by the deformation of mantle rocks. This deformation occurs through the motion of defects in the crystal lattices of minerals. Thus, the physical properties of th.....»»
Researchers forge more open access data for studies of the Earth"s lithosphere
Crust and lithospheric mantle—the thinnest and thickest layers of the Earth's lithosphere—and a wide range of dynamic processes that deform them can be studied by using high precision geodetic data taken directly from Global Navigation Satellite.....»»
