Seismic waves are waves of energy that travel through the Earth's layers, and are
a result of ... Other modes of wave propagation exist than those described in this
article; ... S-waves are slow...
These are the waves that do the most damage to our buildings, highways, etc. ...
To apply those ideas to earthquake studies, think of the earthquake location as
the ... Secondary , or S waves, travel slower than P waves and are also called ...
the time that earthquake rupture initiated (called the "origin time") into the
P wave. S wave. Focus. Play. ｩ2001 How Stuff Works. Epicenter. reset ... waves
move tiny rock particles back and forth -- pushing them apart and then back
together ... How do scientists calculate the origin of an earthquake by detecting
These waves are defined by the type of motion of a particle in the path of the
wave. ... However, the strength of atomic bonds in solids allows them to transmit
... waves varies with their wavelength but always travel slower than P and S
These waves shake the ground as they pass by. ... The location on the surface of
the Earth directly above the focus, or place where an earthquake originates. ...
Slow movement produces aseismic creep. ... magnitude 5 earthquake, for
example, are 10 times greater than those for a magnitude 4 earthquake, 100
times greater ...
As shown in Figure 1, the point on the surface directly above the focus is ... Each
of these waves travel at different velocities (speeds), even though they are
generated simultaneously by an earthquake at the focus (point of origin within the
crust). Since P-waves travel faster than S-waves do, the seismograph will detect ...
These travel slower than P-waves. ... These and other earthquake waves
originate from the focus, which is the actual location of the earthquake's origin. ...
Also, those stations will be able to learn about the interior of the Earth based
upon how ...

The information is then used to determine earthquake locations, the subsurface
structures and etc. .... These waves arrive at seismograph after the arrival of P-
and S-waves ... Love waves (named for A.E.H. Love, who discovered them) travel
by a ..... All is not lost since reflection seismology could detect the slower layer.
Origin of Earthquakes ... These bends disappeared after an earthquake
suggesting that the energy stored in bending the rocks was suddenly ... The
epicenter is the point on the surface of the Earth directly above the focus. ... Note
that S-waves travel slower than P-waves, so they will reach a seismograph after
