Reflection seismology Wikipedia

Reflection seismology (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves.The method requires a controlled seismic source of energy, such as dynamite or Tovex blast, a specialized air gun or a seismic vibrator. Reflection seismology is similar to sonar and

Three-Dimensional Seismic Ahead-Prospecting Method and

Dec 12, 2017 The tunnel seismic ahead-prospecting method is used to estimate adverse geology ahead of the tunnel face. Accurately realizing this geology helps to guarantee safety during construction using a tunnel boring machine (TBM). The paper proposes a three-dimensional (3D) seismic ahead-prospecting method by optimizing a filtering method and an

Seismic Refraction Prospecting for Groundwater: A Case

Jan 18, 2012 Seismic refraction survey method employs seismic energy which bounces back to the surface after traveling through the ground along refracted ray paths (Philip, 2001). Such that the first arrival of seismic energy at a detector source offset from a seismic source always represents either a direct or refracted ray.

The seismic refraction method—a review ScienceDirect

Nov 01, 1974 The seismic refraction method had its beginning in the war of 1914–1918, but it became established as a prospecting method in the 1920's and 30's as a result of successes in the Gulf area of the United States. The success was an outcome of the parallel development of improved instrumentation and improved methods of interpretation.

The seismic method is divided into reflection and refraction techniques, based on whether or not a wave undergoes a reflection at the extent of its travel. Thus, while most refracted events have not been reflected, most reflected events have been refracted, because a refraction occurs across any velocity interface in accordance with the simple
