C. DEFINITION OF TERMS(:
1. Seismograph - a device that records ground movements caused by seismic waves as they
move through Earth.
2. Wave – a disturbance that repeats regularly in space and time (energy) and that is transmitted
from one place to the next.
3. Wave propagation- is any of the ways in which waves travel.
4. Radiate- emit in the form of rays or waves / spread from or as if from a central point.
Engage
- The viewing deck of EDC- Tongonan Geothermal Power Plant
before and after the 6.5 magnitude earthquake hit Ormoc.
- Impacts of the 06 July 2017 M6.5 Leyte Earthquake.
How did Seismologists measure the magnitude of the Earthquake that hit Brgy. Tongonan?
How did they know that there are layers beneath the earth’s surface?
Why does Earth’s crust move?

Q4. Differentiate Love waves from Rayleigh waves.
Q5. Which type of waves do you think were useful to seismologists in their study of the Earth’s interior?
Explain your answer.
Explain
Discuss the following:

Seismic waves – are mechanical vibrations that occur inside the Earth ( along fault lines), which is caused
by the breakage of rocks.
 Seismic waves – energy waves within the Earth
that are released when plates move and travels
through the Earth.
 Seismic waves are classified as surface waves and
body waves.
 Seismic waves from even small earthquakes can
travel around the world.
 Surface wave – the types of wave that travels
through the surface of the Earth (crust or
lithosphere): classified as love and rayleigh waves.
Move more slowly than body waves.

Love wave – is the faster type of surface wave that travel along the surface of the Earth from the
point directly above the epicenter.
the type of wave that move the ground in a side to side manner.
Most damaging type, faster than Rayleigh waves.
Named after a mathematician Augustus Edward H. Love who worked on mathematical models to
demonstrate the propagation of surface waves.
Rayleigh wave – the type of surface wave that moves the ground in a circular manner,
combination of a longitudinal compression and dilation that results in an elliptical motion of
points on the surface.
Move in a circular manner similar to rolling on the ground, causes the ground to move up and
down and side to side.
Causes the ground to shake during an earthquake.
spread out most in time, producing a long wave duration on seismograph.
Named after John William Strutt, also known as Lord Rayleigh, whose mathematical modeling
predicted the possibility of this type of waves.
Body wave – type of seismic wave that travel through the inner layers of the Earth: classified as
Primary (P) waves and Secondary (S) waves.
Primary wave or P-wave – type of body wave that move in a back and forth motion.
- The faster body wave, moves at speeds between 1.5 to 8 km/s.
- compressional waves or longitudinal waves.
- The particles vibrate parallel to the direction of wave motion, the particles are compressed
and stretched.
- Can travel through solid, liquid and gas.
Secondary wave or S-wave – type of body wave that move in an up and down motion.
- transverse waves
- the particles vibrate perpendicular to the direction of wave motion
- slower than P-waves and can travel throug solids only.
- Travels 60% to 70% slower than P-waves.
