Seismic collectors are devices used in the field of geophysics to detect and record seismic waves generated by earthquakes or other sources of ground motion. These devices typically consist of a geophone or accelerometer that converts ground vibrations into electrical signals, which are then recorded and analyzed by seismologists to study the Earth's subsurface structure and seismic activity. Seismic collectors play a crucial role in monitoring and studying earthquakes, as well as in oil and gas exploration, engineering projects, and other applications where knowledge of subsurface geology is important.
