This is the dramatic moment waves crashed onto the Japanese coast after a megaquake struck Russia and triggered a tsunami ...

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.

This is in part because if you were to plunge down 2,700 kilometers (1,700 miles), you would be jump-scared by seismic waves that accelerate when they hit the threshold of the D” layer.

Those seismic waves are like ripples on a pond, the USGS said. The earthquake will be strongest at its epicenter, the point on the surface directly above where the quake started, and the effects ...

Low frequency seismic waves were a key factor in an earthquake in in 1985, when close to 900 buildings in Mexico City, the nation’s capital, partially or totally collapsed.
