Changes in Earth’s Outer Core Revealed by Seismic Waves From Earthquakes
Theory underpins our understanding of convection in the Earth’s outer core and its function in controlling the planet’s magnetic field. Convective flows or how they…

New research led by the University of Cambridge is the first to obtain a detailed ‘image’ of an unusual pocket of rock at the boundary…
NASA’s InSight lander’s seismometer on Mars has recorded two of its strongest seismic events to date: a magnitude 4.2 and a magnitude 4.1 marsquake. The…
High resolution illumination of Earth’s interior down to the planet’s core with 3D global numerical simulations. Earthquakes do more than buckle streets and topple buildings….
Earthquakes themselves affect the movement of Earth’s tectonic plates, which in turn could impact on future earthquakes, according to new research from the University of…
Researchers have uncovered the most detail ever of the mysterious structures laying between the Earth’s mantle and core, also providing the strongest evidence yet they…
The dramatic collapse of Indonesia’s Anak Krakatau volcano in December 2018 resulted from long-term destabilizing processes, and was not triggered by any distinct changes in…
A simulation of the evolution of the Earth’s interior over time, showing the thermal (bottom), chemical (middle), and thermochemical evolution under the simulated conditions. The…
Earthquakes of similar magnitude can cause tsunamis of greatly varying sizes. This commonly observed, but not well-understood phenomenon has hindered reliable warnings of local tsunamis….
There might be a quadrillion tons of diamonds 100 miles below Earth’s surface. But the farthest we’ve traveled is 7 miles down, so how could…
Seismic data collected in Elysium Planitia, the second largest volcanic region on Mars, suggest the presence of a shallow sedimentary layer sandwiched between lava flows…
Applied in the field, a new model reduced quakes from oil and gas processes; could help manage seismic events from carbon sequestration. When humans pump…
In March 2020, daily life in the United States changed in an instant as the country locked down to deal with the initial wave of…
A team of researchers understands more about the melting of the Greenland ice sheet. They discovered a flow of hot rocks, known as a mantle…
Using data from NASA’s InSight Lander on Mars, Rice University seismologists have made the first direct measurements of three subsurface boundaries from the crust to…
Global COVID-19 “lockdown” measures — the quarantines, physical isolation, travel restrictions and widespread closures of services and industry that countries around the world have implemented…
University of Maryland researchers conduct first simultaneous analysis of hundreds of earthquakes to identify echoes from features deep inside Earth. University of Maryland geophysicists analyzed…
New seismic array is sensitive enough to distinguish individual floats and bands. In November, Caltech and the City of Pasadena unveiled a new citywide fiber…
