Mantle upwelling may have triggered Morocco earthquake
On 8 September 2023, a magnitude 6.8 earthquake struck western Morocco, causing damage and destruction that claimed thousands of lives in rural communities in the High Atlas Mountains......»»
Researchers discover dual epicenters in New Year"s Day Noto earthquake
The first seven months of 2024 have been so eventful, it's easy to forget that the year started off with a magnitude 7.5 earthquake centered beneath Japan's Noto Peninsula on New Year's Day. The earthquake killed more than 280 people and damaged more.....»»
Floods swamp Bangladesh as nation finds its feet after protests
Floods triggered by torrential rains have swamped a swath of low-lying Bangladesh, disaster officials said Thursday, adding to the new government's challenges after weeks of political turmoil......»»
Multidirectional negative-stiffness isolation system offers improved seismic protection
Seismic isolation is crucial for safeguarding buildings from earthquake damage. While traditional systems are effective, they struggle with multidirectional forces and adequate damping. These challenges highlight the need for innovative solutions tha.....»»
Exoplanets may contain more water than previously thought
We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets—planets that orbit another star outside our sol.....»»
Geophysicists find link between seismic waves called PKP precursors and strange anomalies in Earth"s mantle
For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth's lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds......»»
Japan"s first-ever megaquake advisory brings worry and confusion. What does it mean?
Japan, one of the most earthquake-prone nations on earth, issued its first-ever "megaquake advisory" last week after a powerful quake struck off the southeastern coast of the southern main island of Kyushu......»»
What to know about the MyShake app, California"s earthquake warning system
With the unpredictable and destructive nature of earthquakes, a few extra seconds of notice can make all the difference in the world......»»
Studying the journey, not the destination, provides new insight into songbird migrations
Migration is an adaptive phenomenon, typically triggered by a change of season, that is vital to ecosystem health. Animals may journey thousands of miles, in some cases, in search of food, better living conditions, or to find a mate. Conversely, huma.....»»
New parameter enhances insights into the evolution of mantle"s redox states
The oxygen fugacity (fO2) of the mantle controls the speciation and mobility of volatiles within it, influencing the composition of volatiles released during mantle-derived magmatic activity, and thereby regulating the composition of the atmosphere......»»
The biggest-ever sample of core material from Earth"s mantle could have valuable clues into the origins of life
If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, enclosed within the mantle is the innermost metallic c.....»»
Study reveals Canadian wildfires are affecting US air quality and raising health concerns
Rutgers researchers examined particulate matter from a June 2023 fire that triggered advisories for more than 100 million Americans in the Northeast......»»
Japan "megaquake" advisory after tremor injures eight
Japan's earthquake scientists have warned of the possibility of a coming "megaquake" after eight people were injured Thursday by one of magnitude 7.1 in the south......»»
Japan"s "megaquake" warning explained
Japan's earthquake scientists say the country should prepare for a possible "megaquake" one day that could kill hundreds of thousands of people—although they stress the warning does not mean a colossal tremor is imminent......»»
Recovery of rocks that originated in Earth"s mantle could reveal secrets of planet"s history
Scientists have recovered the first long section of rocks that originated in the Earth's mantle, the layer below the crust and the planet's largest component......»»
A powerful earthquake hits off southern Japan; tsunami advisory issued

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......»»
