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 ...

Specifically, PKP waves are P-waves that have traveled through the Earth's mantle and core, and arrive at the surface at a variety of speeds depending on how far they traveled through these layers.

Researchers have mathematically elucidated how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. A novel equation was derived to describe the travel of ...

These factors can locally intensify the seismic waves, therefore leading to additional damage. “In the 1906 California earthquake, some people living 100 miles away slept through the quake ...

S waves are more dangerous than P waves because they have greater amplitude and produce vertical and horizontal motion of the ground surface. The slowest waves, surface waves, arrive last. They travel ...

Moreover, there is little high-resolution observation on how tidal forces affect the changes in seismic wave speed within the fault zone over time.

A new animation shows just how this might play out beneath the surface of Mars. Scroll down for video Scientists have simulated the path of seismic waves rippling across the red planet.

There are three types of seismic waves – P waves, S waves and surface waves. P waves are longitudinal waves, and their relative speed is faster than other waves.

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 ...
