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 ...
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.
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 ...
Seismic readings of the interior of Mars strongly suggest large quantities of water buried 6 to 12 miles underground.
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 ...
Mars might hold enough subsurface water to cover its surface in a global ocean between 0.62 to 1.24 miles (1 to 2 kilometers) ...
