ABSTRACT:
A man-portable, easily disassembled seismic source is described which utilizes a self-propelled projectile. The projectile, carrying a container of compressed gas, is supported over a rigid earth-contacting target at one end of a lightweight linear guide or track. When the support is removed, the container is automatically vented to atmosphere in an upward direction. In this way, the projectile is jet-propelled to the target, which in turn produces an acoustic pulse in the earth.
