According to physics, seismic waves from earthquakes should travel in a four-leaf clover pattern, but in the real world they behave more like ripples in a pond. New research has found the pattern ...

Samuel’s team went beyond considerations of density, composition, and seismic velocity and looked at how the interior structure of Mars attenuated seismic waves. “From this, we were able to infer the ...

Microseisms – which are observed globally – may either travel across the surface of the Earth, or through its interior as body waves. Like the seismic waves generated by earthquakes, these body waves ...

Seismic waves help scientists 'see' chemical changes beneath a watershed Date: July 27, 2020 Source: Penn State Summary: Chemical reactions deep below ground affect water quality, but methods for ...

Seismic waves slow down significantly by 5 to 10 percent between the lithosphere and asthenosphere. ... He covers all things human origins and astronomy as well as physics, ...

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 ...

The first studies of the 28 March 2025 magnitude 7.8 Myanmar earthquake suggest that the southern portion of its rupture ...

You can't feel it, but there's a constant, low frequency vibration that's reverberating throughout the planet. It's not an earthquake. It’s more like a continuous humming or ringing, as if ...

Chemical reactions deep below ground affect water quality, but methods for 'seeing' them are time-consuming, expensive and limited in scope. A Penn State-led research team found that seismic waves ...
