Scientists have discovered that seismic waves traveling to Earth’s core and back caused almost all of Japan to shift eastward ...

Sedimentary basins—depressions in Earth's crust caused by tectonic activity—tend to be flat and are favored places to build ...

The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

A remote-sensing technique that can detect real-time changes in subsurface environments has undergone successful testing in the desert just outside the KAUST campus in Thuwal, Saudi Arabia. To avoid ...

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 ...

Seismic full-waveform inversion (FWI) for imaging Earth’s interior was introduced in the late 1970s. Its ultimate goal is to use all of the information in a seismogram to understand the structure and ...

Mars has had its first CT scan, thanks to analyses of seismic waves picked up by NASA’s InSight lander. Diagnosis: The Red Planet’s core is at least partially liquid, as some previous studies had ...

(Grant Faint/The Image Bank/Getty Images) When the magnitude 9.0 Tōhoku earthquake struck off the coast of Japan in 2011, its ...
