Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

In 2024, scientists made headlines when they found evidence of copious amounts of water inside a layer of the Martian crust.

When seismic waves travel through or bounce off different materials inside the Earth, they carry information that can help researchers infer the composition and behavior of those materials.

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other ...

Instead, scientists map the interior by watching how seismic waves from earthquakes are bent, reflected, sped up, or delayed by the various layers.

Seismic waves – WJEC Earthquakes produce shockwaves called seismic waves. These waves can be detected using seismographs. Some seismic waves are surface waves, while others can travel through ...

understanding the behavior of these seismic events is crucial for mitigating risks and enhancing preparedness. In recent years, it has become evident that the energy transported by seismic waves ...

A new analysis of earthquake rupture directivity provides essential insights for seismic hazard and risk assessments in urban areas, particularly ...
