Answer and Explanation:A travel-time graph can be used to find the distance from an area experiencing an earthquake to the epicenter of the earthquake.
Which seismic waves are the most destructive?
Although surface waves travel more slowly than S-waves, they can be much larger in amplitude and can be the most destructive type of seismic wave. There are two basic kinds of surface waves: Rayleigh waves, also called ground roll, travel as ripples similar to those on the surface of water.
Which seismic waves compress and expand rocks in the direction the waves travel?
There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel.
What produces a record of seismic waves?
Seismograph, instrument that makes a record of seismic waves caused by an earthquake, explosion, or other Earth-shaking phenomenon. A record produced by a seismograph on a display screen or paper printout is called a seismogram.
What measurement for earthquakes do scientists use most often today?
moment magnitude scale
What are 4 types of seismic waves?
Types of waveSeismic waves are fundamentally of two types, compressional, longitudinal waves or shear, transverse waves. Through the body of the Earth these are called P-waves (for primary because they are fastest) and S-waves (for secondary since they are slower).
What is the most dangerous type of earthquake?
Love waves are the most dangerous of all kinds of seismic waves. They are faster than Rayleigh waves and even larger in amplitude.
How do P and S waves travel?
How do P and S-waves move? P-waves are the fastest waves created by an earthquake. They travel through the Earth’s interior and can pass through both solid and molten rock. They shake the ground back and forth – like a Slinky – in their travel direction, but do little damage as they only move buildings up and down.
Which seismic waves travel the fastest?
The fastest seismic wave is the primary wave, or the P-wave. These waves move through solid rock and liquid rock alike at high speeds, since they
Which is faster S or P wave?
P-waves and S-waves are body waves that propagate through the planet. P-waves travel 60% faster than S-waves on average because the interior of the Earth does not react the same way to both of them. The energy is thus less easily transmitted through the medium, and S-waves are slower.
