Different Types of Seismic Waves download lecture slides P Waves primary waves first to arrive at a seismic station compressional waves a type of seismic wave that travels straight through Earth from EQ to station (body wave) particle motion in the direction of wave propagation somewhat equivalent to sound waves (acoustic waves) S Waves secondary waves second to arrive at a seismic

The most common way is using seismic technology which sends sound waves into the earth and uses geophones to receive the sound waves when they bounce back and analyzing seismic data to simulate stratum characteristics Simulation is used to determine whether there are rocks containing oil and gas This thesis devotes efforts to explain the whole detecting process as well as details in

Just like my voice travels through the air via sound waves seismic waves travel through rocks in the Earth's crust she explains By sending a vibration into the Earth and measuring the time that it takes for a wave to travel through the subsurface from one location on Earth to another location on Earth Dr Martinez says we can start to try to understand what lies hidden beneath us

A seismic source is a device that generates controlled seismic energy used to perform both reflection and refraction seismic surveys A seismic source can be simple such as dynamite or it can use more sophisticated technology such as a specialized air gun Seismic sources can provide single pulses or continuous sweeps of energy generating seismic waves which travel through a medium such as

Seismic refraction and reflection methods measure the transmission of sound waves through the subsurface generated using a hammer blow or explosive energy source Individual subsurface layer depths and thickness can be calculated based on the analysis of sonic wave arrival times

Deep seismic surveying

Seismic waves are produced by large movements of earth events like earthquakes volcanic eruptions landslides and man-made explosions can produce seismic waves These waves can be travel through the bedrock and can be used to image both sources and structures deep within the Earth P- and S-waves There are three basic types of seismic waves in solids P-wave and S-wave (both body waves

a typical prospecting experiment sound waves generated by small explosions travel from a source on the surface into the ground and are reflected back by the complex structures beneath the surface which we refer to as reflectors These reflectors represent the surfaces where the stratigraphy changes The reflected waves are

Seismic prospecting is conducted either on land or at sea Seismic waves are generated by chemical explosions or vibrating impacts of short duration By recording the time history of the reflected seismic waves information on the nature and geological significance of the Earth's interior can be obtained
