WebS Waves, known as Secondary Waves, are seismic waves that simply go about in an S shape, form, and is the second wave to arrive during an earthquake. S waves cannot travel through liquids, they can travel through solids. P waves, known as Primary waves, are also part of a seismic wave. This waves comes first during an earthquake, it is the ... WebPrimary waves, also known as P waves or pressure waves, are longitudinal compression waves similar to the motion of a slinky (SF Fig. 7.1 A). Secondary waves, or S waves, are slower than P waves. The motion of secondary waves is perpendicular to the direction of the wave travel, similar to the motion of vigorously shaking a rope (SF Fig. 7.1 B). WebThe motion of Rayleigh waves is quite complex. On Mars, SEIS will use these waves to locate quakes, a feat impossible for a single seismic station waiting to record body waves. Unlike its counterparts on Earth, which form part of a large network made up of thousands of seismic stations, the SEIS seismometer placed on the Martian surface by ... try new smartphones coming out soon

Rayleigh waves are the slowest of all the seismic wave types and in some ways the most complicated. WebThere are different types of seismic waves, including body waves (P-waves and S-waves) and surface waves (L-waves or Love waves and R-waves or Rayleigh waves). Earthquakes can be measured using the Richter Scale, which is a logarithmic scale that measures the energy released by an earthquake.
