Abstract
An improved portable seismic energy source including a base member having cylindrical sidewalls and an open lower end for resting on the earth's surface, a horizontal baseplate secured to the base member upper end, the baseplate having a central opening therein, a gun mounted on the horizontal baseplate for firing a projectile through the opening therein to impact the earth's surface and generate a seismic signal, a spatter plate mounted to the base member such as by means of a vertical cylinder secured to the lower surface of the baseplate with the lower end of the cylinder being affixed to the spatter plate, the spatter plate having an opening therein in register with the cylinder so that a projectile fired passes through the opening, the spatter plate being positioned above the earth's surface, and a flexible diaphragm secured at its periphery to the lower circumferential surface of the base member and having a central opening therein, the diaphragm being stretched over the top of the spatter plate, the spatter plate and diaphragm serving to intercept gas, liquids, and solid objects which are ejected when a projectile is fired to generate a seismic signal.
