In this lesson, students learn about different types of seismic waves on the basis of where and how the waves move. In addition, students discuss how scientists use earthquake waves to investigate ...

Researchers examining seismic data recorded on Mars say the have found evidence supporting the presence of liquid water deep ...

Full Waveform Inversion (FWI) is capable of finely characterizing the velocity structure, anisotropy, viscoelasticity, and attenuation properties of subsurface media, which provides critical ...

Most scales are based on the amplitude of seismic waves recorded on seismometers ... the building (or other structure) design, and the type of surface material (rock or dirt) the buildings rest on.

Seismic waves can travel much farther through the Eastern type of rock — which is old, cold, and dense — before they decay and dissipate. "Earthquakes on the East Coast are felt much further ...

The core itself consists of a solid inner core and a liquid outer core. There are three types of seismic waves – P waves, S waves and surface waves. P waves are longitudinal waves, and their ...

A recording of an earthquake has recognizable characteristics. Typically, one can recognize the arrival of different wave types. The P waves (the fastest traveling waves), S waves, and Surface waves ...

A surface wave travels along the surface of the Earth. It is the slowest of the three types of seismic wave. Surface waves usually have larger amplitude than the other waves and cause the most damage.

Researchers have found new evidence for a massive subsurface ocean on Mars, again raising the possibility of microbial life.
