This surface wave propagates parallel to the interface and decays exponentially vertical to it, a property known as evanescence. C These travel slower than S waves and P waves but have large amplitudes which could much ground motion and cause huge destruction. Point 1 is the focus, Point 2 is the epicenter, and Line 3 is the fault. When scientists mention surface waves, they are typically referencing Love waves and Rayleigh waves, which are the two primary seismic waves that travel on the surface rather than through the mantle and core of the earth, like seismic body waves do. 2.

Seismic waves from this earthquake are detected at a variety of seismographs worldwide. The _______________ of an earthquake refers to the breakage point of subsurface rock resulting in the creation of the epicenter. D.) A wave bounces off the surface of a material. In radio transmission, a ground wave is a guided wave that propagates close to the surface of the Earth.[1]. The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. (C) They are produced by P and S waves. Thus far, we have defined surface waves as being caused by an earthquake, using the definition of an earthquake as the release of energy. A Rayleigh wave is a surface wave that exhibits both transverse and longitudinal motion, similar to a water wave. While most surface waves are mechanical waves, which means they must travel through a specific material, some electromagnetic surface waves do exist. Select three options.

After both P and S waves have moved through the body of Earth, they are followed by surface waves, which travel along Earths surface. (c) They travel through solids. The body waves travel faster and along a shorter path than the surface waves, so they will arrive at a location first regardless of the distance from the earthquake's epicenter. Earthquakes are usually caused when rock underground suddenly breaks along a fault. c. Its temperature is too high to be pure iron.
