Traveling through the interior of the Earth, body waves arrive before the surface waves emitted by an earthquake. These waves are higher frequency than surface waves. P waves are also known as ...

The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

Researchers show that fish, through precise control of body fluctuations, generate movable vortex pairs of high- and low-pressure regions that enable them to swim. They used particle image velocimetry ...

A continuously swimming mullet modulates its thrust production by changing slip-the ratio between its swimming speed U and the speed V with which the body wave travels down its body. This variation in ...

On the morning of November 11, just before 9:30 UT, a mysterious rumble rolled around the world. The seismic waves began roughly 15 miles off the shores of Mayotte, a French island sandwiched between ...
