New analysis of satellite altimetry data reveals that trapped waves called seiches were responsible for anomalous seismic ...

In September 2023, a global seismic mystery began to unfold. Every 90 seconds, the Earth pulsed with a strange, low-frequency vibration that lasted for nine days straight. Then, just when scientists ...

Earth’s mucilaginous mantle, slowly flowing beneath the crust, was first detected in 1889 from the movement of seismic waves. The liquid outer core was identified in 1914 , and the solid inner ...

Both ultrasound for medical imaging and seismology for imaging the Earth's interior measure the propagation of waves through matter. For example, when seismic waves encounter material differences ...

Changes in seismic wave speed and direction can result from gradual variations in rock temperature or density, for example. Mars’ seismic waves also hint at the thickness of the planet’s crust.
