Seismology is the study of Earth's vibrations. Earthquakes, extra-terrestrial collisions, explosions, storm waves hitting the beach, and tidal effects are all examples of occurrences that create vibrations. Studies of earthquake environmental consequences like tsunamis, as well as seismic causes including volcanic, tectonic, glacial, fluvial, oceanic, atmospheric, and manmade processes like explosions, are all part of the field. Paleo seismology is a similar subject that uses geology to deduce information about past earthquakes. A seismogram is a recording of earth motion as a function of time. A seismologist is a scientist who studies earthquakes. Based on the energy source of the seismic waves, the approaches are divided into two groups. Earthquake seismology is a branch of science that studies the physical properties, composition, and gross interior structure of the Earth as a result of natural shock waves. Explosion seismology is the study of regional and local structures using manufactured blasts such as (1) detonating a dynamite charge (land) and (2) nonexplosive vibriosis or compressed air (marine).
