Seismic migration is a process of estimating earth's reflectivity from a recorded seismic wavefield using a ...

Seismic velocity is assumed usually to increase with increasing depth and when measured in a vertical direction it may be 10-15% lower than when measured parallel to strata. The velocities of various rock types vary rather widely so it is usually difficult to determine rock type based only upon velocities.

The water level might remain higher or lower for a period of time after the seismic waves end, but sometimes a long-term offset of groundwater levels follows an earthquake. The largest recorded earthquake-induced offset in a well is a one meter rise.Seismic waves are vibrations generated by sudden movements of rock. After earthquakes occur, the seismic waves propagate from the hypocentre to the surface of the Earth. The speed at which the waves propagate is a function of the nature and type of rock traversed, but generally varies from 1 to 10 km/s. Marine seismologists use sound to map and characterize ocean sediment layers. An airgun is a device used to examine the layers of the seafloor. It is designed to release compressed air, which forms a bubble. The air released by an airgun produces a loud sound, which reflects off the seafloor and can be detected by hydrophone s.
