Seismic methods are techniques based on the measurement and study of the propagation of seismic waves. Precisely, seismic methods measure the elastic properties of soils and rocks that are a function of the physical properties such as seismic velocity, density, and shear modulus.

Seismic methods consist of different data acquisition and processing techniques, depending on the project’s goal. A seismograph, a string of receivers (geophones), and a seismic source are the components of a seismic data acquisition system. Each seismic technique can yield new insights into the subsurface. The seismic survey can be performed on the ground, in boreholes, or marine environments.

Cordillera Geo-Services offers the following land seismic methods to solve various problems: refraction (tomography), reflection, MASW, ReMi, and borehole seismic methods (downhole seismic, crosshole seismic, seismic tomography.) Typical applications of these methods include:

Seismic Methods

Seismic techniques (including seismic refraction, seismic reflection, and shear wave analyses) have been used by geophysicists for over 100 years to image the subsurface. These reliable techniques determine various properties of the subsurface that are used for different applications in engineering, construction and hydrogeology.

Seismic methods involve the recording of seismic waves (both naturally occurring and generated) for detecting subsurface interfaces and measuring seismic velocity variations with depth. A typical seismic acquisition system consists of a series of seismograph, a series of geophones, and (depending on the technique) an energy source, which is generally a sledge hammer hitting against a metal plate on the ground or a small explosive device.

Mundell & Associates has conducted seismic surveys in North and South America, as well as Europe, for purposes such as mapping bedrock fracture zones, locating bedrock valleys, and characterizing sites for earthquake design.
