seismic tomography
Seismic tomography is a geophysical imaging technique used to study the subsurface structures of the Earth using seismic waves. It involves collecting data from seismic waves that are generated by earthquakes or controlled sources, and then analyzing and interpreting the data to create images or models of the subsurface.
The technique relies on the principle that seismic waves travel at different speeds through different geological materials. By measuring the arrival times and amplitudes of seismic waves at various geophone stations, scientists can determine the velocity of the waves at different locations.
Seismic tomography can be used to study a variety of subsurface features, including the Earth's crust, mantle, and even the core. It can provide valuable information about the composition, density, temperature, and other properties of these layers.
In addition to its use in understanding the Earth's structure, seismic tomography has practical applications in fields such as mining, oil and gas exploration, and geothermal energy development. It helps in locating and characterizing underground reservoirs, faults, and other geological structures.
Overall, seismic tomography is a powerful tool in geophysics that allows scientists to gain insights into the Earth's interior and contribute to our understanding of its formation and dynamics.
