As the two powerful tremors lined up on the Mid-Atlantic Ridge, one expert believes such an event could set off a terrifying ...

Seismic data captured by ocean-bottom instruments have revealed "fossilized" traces of mantle flow beneath the Pacific ...

Seismic wave dynamics in tectonic systems encompass the generation, propagation and interaction of elastic disturbances within the Earth’s lithosphere and underlying mantle. At their source, rapid ...

Assistant Professor Chukwuebuka Nweke explains how the region’s sedimentary basins can amplify seismic waves – and why ...

The study of earthquakes called Seismology, relies on the fact that different materials within the Earth react differently to stress. When a fault slips, energy radiates outward from the focus (the ...

A better understanding of how earthquakes occur and what happens during a rupture is important for assessing seismic risk.

As oceans waves rise and fall, they apply forces to the sea floor below and generate seismic waves. These seismic waves are so powerful and widespread that they show up as a steady thrum on ...

Scientists have known that seismic waves slow down when passing through ultra-low velocity zones, or ULVZs, but only knew they existed around hotspots that create volcanic island chains. Now, a new ...

The mechanism facilitating the smooth movement of the oceanic lithosphere over the underlying asthenosphere (upper mantle) remains poorly understood. Recently, researchers from Japan investigated the ...

Mars may have a hardened heart. Marsquake reverberations detected by NASA’s InSight lander revealed that the Red Planet probably possesses a solid inner core, researchers report in the Sept. 4 Nature.

Mars’ heart is about the size of our moon, and almost twice as dense. Or so suggest the first observed rumblings from a Marsquake and meteorite impact to cross the Red Planet’s heart, researchers ...
