The aim of seismic data acquisition is to deliver products that mimic cross-sections through the earth. In order to do this, the correct amount and types of data must be acquired, and applied to remove unwanted energy and to place the required events in the correct location. At the same time, a balance needs to be struck between cost and timeliness of data, while attaining also the important objectives of safe operations and doing no harm to the environment. It is an initial work to detect geological structures of the seabed.
Seismic design and analysis is a subset of structural analysis and is the calculation of the response of a building structure to earthquakes. It is part of the process of structural design or structural assessment and retrofit in regions where earthquakes are prevalent.
Seismic imaging directs an intense sound source into the ground to evaluate subsurface conditions and to possibly detect high concentrations of contamination. Receivers called geophones, analogous to microphones, pick up echoes that come back up through the ground and record the intensity and time of the echo on computers. Data processing turns these signals into images of the geologic structure. This technology is similar in principle to active electromagnetic survey technology.
