Seismic waves generated by natural or artificial sources traverse Earth’s interior, their speeds and paths controlled by variations in elastic properties, density and temperature. Compressional (P) ...

Tsukuba, Japan—A recent study has mathematically clarified how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. The researchers derived a new equation that ...

Seismic interferometry exploits the continuous background of ambient seismic noise or controlled sources to recover the impulse response between pairs of receivers, effectively turning one sensor into ...

Solid as they are, rocks are not static materials with constant properties. Even small loads are enough to alter their mechanical properties; their reaction to being deformed is a loss of stiffness.

Rock sample of Bentheim sandstone, inside a protective neoprene jacket and with all the sensors glued to its surface, before going into GFZ's experimental press. Solid as they are, rocks are not ...
