Strength of reflection depends on

Seismic speed contrast across interface

Density contrast across interface

Transmitted energy can be partially reflected by still-deeper interfaces

Travel-time, strength of "echoes" from layers below source measured

Travel-times give relative depth

Strength gives property contrast

Repeated at close spacings along profile (compare echo-sounder)

Result is seismic section, which mimics layer distribution in subsurface

Major tool in oil,gas exploration

Hydrocarbons trapped in deformed beds (for example, folds, domes)

Relative travel-time of reflections shows relative depths

Structural interpretation possible up to several km below surface

Seismic signal processing techniques focus on improving signal-to-noise
