Seismic trace

A seismic trace is a time-series representation of seismic data recorded by a seismometer or geophone during a geophysical survey. Each trace corresponds to a specific location on the Earth's surface where seismic waves are detected, typically generated by a controlled source like an explosion or a vibrating machine. Seismic traces are fundamental components of seismic data and are usually organized in a two-dimensional or three-dimensional grid to represent subsurface geological structures.
