NOTES

Seismology is the study of elastic waves, and sound waves that pulse through the earth. These waves are are often known as Earthquakes.
(PG, 9)……….Seismology and society
This study impacts the world we know in cases like exploration of the earth for more resources, the study of earthquakes, and even nuclear arms.
Earthquakes are measured using a tool known as the siesmograph. Earthquakes are also rated on a scale known as the Richter Scale that goes from one though 10
earthquakes are mostly caused by faults shifting, pulling apart, or pushing together

NOTES

An ancient Japanese folktale states that earthquakes were cause by a giant cat fish beneath the surface of the earth.
An earthquake can produce different kinds of waves like S waves, and P waves.
P waves are where when an earthquake passes the surface of that area will compress and dilate.
While with S waves the ground gives the impression that the surface is moving in a wave formation.
when an earthquake occurs under the surface the point is known as the Focus, while the point the earthquake occurs above the Focus is known as the Epicenter.
