• This is a template to create an Instructional
  Design Document of the concept you have selected
  for creating animation.
• This will take you through a 5 section process to
  provide the necessary details to the animator
  before starting the animation.
• The legend on the left will indicate the current
  status of the document. The Black coloured number
  will denote the current section, the Turquoise
  color would denote the completed sections, and
  the Sky blue color would denote the remaining
  sections.
• The slides having 'Instructions' would have a
  Yellow box, as shown on the top of this slide.

• Seismic Waves- These are energy waves caused by
  an impulse such as sudden breaking of rocks
  within the Earth or an explosion. Seismic waves
  are of two types Seismic Body Waves Seismic
  Surface Waves
• Seismic Body Waves- These are elastic waves that
  propagate through the Earth's interior. In
  reflection and refraction prospecting, body waves
  are the source of information used to image the
  Earth's interior. Like the ripples on the surface
  of the pond example described previously, body
  waves propagate away from the source in all
  directions. If the speed at which body waves
  propagate through the Earth's interior is
  constant, then at any time, these waves form a
  sphere around the source whose radius is
  dependent on the time elapsed since the source
  generated the waves. There are two types of body
  waves Compressional (P) hear (S)

• Seismic Surface Waves- Travels through just under
  the Earth's surface slowly, as compared to body
  waves. They are low in frequency, long in
  duaration large in amplitude. There are two
  types of surface waves Love ave Rayleigh Wave

Definitions and Keywords

• P, Compressional, Primary, Longitudinal- P waves
  are also called primary waves, because they
  propagate through the medium faster than the
  other wave types. In P waves, particles
  constituting the medium are displaced in the same
  direction that the wave propagates, in this case,
  the radial direction. Thus, material is being
  extended and compressed as P waves propagate
  through the medium. P waves are analogous to
  sound waves propagating through the air.
• S,  Shear, Secondary, Transverse- S waves are
  sometimes called secondary waves, because they
  propagate through the medium slower than P waves.
  In S waves, particles constituting the medium are
  displaced in a direction that is perpendicular to
  the direction that the wave is propagating.

Definitions and Keywords

• L, Love, Surface waves, Long waves- These waves
  occur when the shear-body-wave velocity in the
  surface medium is lower than that in the
  underlying strata. Love waves are characterized
  by horizontal motion normal to the direction of
  travel, with no vertical motion.These waves,
  which in contrast to P- and S-Waves do not travel
  through the interior of the Earth, they race
  along its surface instead. They also come in two
  varieties which differ in at least two aspects
  the particle motion they generate and the speed
  with which they circle the globe.
• R, Rayleigh, Surface waves, Long waves, Ground
  roll- These waves are a type of surface acoustic
  wave that travels on solids. They are produced on
  the Earth by earthquakes, in which case they are
  also known as "ground roll", or by other sources
  of seismic energy such as an explosion or even a
  sledgehammer impact

Caption for Fig 2
Deformation propagates. Particle motion consists
of alternating compression and dilation.
Particle motion is parallel to the direction of
propagation (longitudinal). Material returns to
its original shape after wave passes.
Show a band (as shown with magenta colour in
the figure), starting from the left of the
figure, which will move through the grids to the
right. When it reaches the black block
it'll move it in such a way that 1st it goes
ahead a liitle then moves back a little at
last settles down at its original location.

Particle Motion
Alternating compressions (pushes) and
dilations (pulls) which are directed in the
same direction as the wave is propagating

perpendicular to the wavefront. Contd in

P motion travels fastest in materials, so the
P-wave is the first-arriving energy on a
seismogram.  Generally smaller and higher
frequency than the S and Surface-waves.  P waves
in a liquid or gas are pressure waves, including
sound waves.

A wave will be shown starting from the left wall
of the fig to the right resembling the arrows
directing the wave motion.When the wave
reaches the black block it'll be moved in such
a way that at 1st it'll move up then down and
will rest in its original position. Refer to the
2nd link in slide no. 25. to get a clear idea.
Deformation propagates. Particle motion consists
of alternating transverse motion. Particle
motion is perpendicular to the direction of
propagation (transverse). Transverse particle
motion shown here is vertical but can be in any
direction. However, Earths layers tend to cause
mostly vertical (SV in the vertical plane) or
horizontal (SH) shear motions. Material returns
to its original shape after wave passes

S-waves do not travel through fluids, so do not
exist in Earths outer core (inferred to be
primarily liquid iron) or in air or water or
molten rock (magma).  S waves travel slower than
P waves in a solid and, therefore, arrive after
the P wave.

Wave will move from left to right.When the wave
reaches the black red blocks they'll move up
down but will move along with the wave from
left to right. The wave will move in such a
way that movement will be maximum near
the surface the motion will decrease slowly
as it goes down the grid. This means the middle
layers of the grid will have lesser move -ment
than the upper ones bottom grids will have
minimum movement. The black block will have max
movement and red one will have min movement
Deformation propagates. Particle motion consists
of alternating transverse motions. Particle
motion is horizontal and perpendicular to the
direction of propagation (transverse). To aid in
seeing that the particle motion is purely
horizontal, focus on the Y axis (red line) as the
wave propagates through it. Amplitude decreases
with depth. Material returns to its original
shape after wave passes.

Love waves exist because of the Earths
surface. They are largest at the surface and
decrease in amplitude with depth. Love waves are
dispersive, that is, the wave velocity is
dependent on frequency, generally with low
frequencies propagating at higher
velocity. Depth of penetration of theLove
waves is also dependent on frequency, with lower
frequencies penetrating to greater depth.

Wave will flow from left to right.The black
block turquoise block moves together in an
elliptical path, making an anti-clockwise
rotation from right to left. The ellipse made
bythe black' black lock will be bigger in size
than that of the turquoise block. The movement
of waves wil lreduce with depth of the rided bar.
This means, he grids nearer to the urface at the
top will ove more than those at the
bottom. Visit the link below to get a clear idea

is generally elliptical either prograde or
retrograde.

of elliptical motions (generally
retrograde elliptical)in the vertical plane and

Rayleigh waves are also dispersive and
the amplitudes generally decrease with depth in
the Earth. Appearance and particle motion are
similar to water waves. Depth of penetration of
the Rayleigh waves is also dependent on
frequency, with lower frequencies penetrating
to greater depth. Generally, Rayleigh waves
travel slightly slower than Love waves.
