Reflection and refraction seismology can be used in geophysical exploration to locate layers of varying density which can be used for example to locate underground hydrocarbons in the oil and gas industry.

Seismology has also provided us with information on the internal structure and state of matter of the interior of the Earth.

a) Seismology earthquake occur along plate boundaries , on faults and in volcanic areas while seismology exploration was create by artificial sources like explosion. Besides seismology earthquake make lot destruction than seismology exploration.

Seismology is the study of the motions of the Earth's crust.
