Deep underground flooding beneath hot springs: A potential trigger for the 1995 Kobe earthquake
Researchers at University of Tsukuba have shown that the 1995 Kobe (Hyogo-ken Nanbu) earthquake, which struck southern Hyogo Prefecture, may have been triggered by deep underground flooding beneath Arima Hot Springs. By analyzing the stable isotope r.....»»
Climate change-triggered landslide unleashes a 650-foot mega-tsunami
In September 2023, scientists around the world detected a mysterious seismic signal that lasted for nine straight days. An international team of scientists, including seismologists Alice Gabriel and Carl Ebeling of UC San Diego's Scripps Institution.....»»
Precariously balanced rocks in New York, Vermont provide limits on earthquake shaking
Five boulders, delivered by glacier and balancing delicately on rocky pedestals in northern New York and Vermont, can help define long-term maximum shaking intensity of earthquakes in the region......»»

Algorithm raises new questions about Cascadia earthquake record
The Cascadia subduction zone in the Pacific Northwest has a history of producing powerful and destructive earthquakes that have sunk forests and spawned tsunamis that reached all the way to the shores of Japan......»»
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.....»»
