This article is about artificial seismic sources.

For natural seismic sources, see Earthquake, Volcano, and related articles.

A hammer blow or small explosive (black powder) are typically used for the seismic source.

Thus, it would seem possible to increase the signal by using stronger seismic sources.

A fourth experiment involved geophysical studies based upon the timed seismic source.

As such, it is possible to obtain information about the subsurface with no need for an active seismic source.

It is one of a number of seismic sources used in reflection seismology.

This equipment consists of a seismograph, geophones placed in an array, and a seismic source.

Rayleigh waves are generated from seismic sources described to be active, passive, or a combination of both.

His detonation wave technology has applications in propulsion, weapons and as a high energy impulse seismic source.
