A system for providing seismic excitation for subsurface monitoring, the system can include a vertical shaft extending into the ground, an unassisted weight-drop mechanism disposed within the shaft and configured to release a weight from a drop height, where an unassisted weight-drop mechanism disposed within the shaft and configured to release a weight from a drop height, where the unassisted weight-drop mechanism is operably configured to retrieve the weight from the base of the shaft, and raise the weight to the drop height; an engineered impact plate assembly located at the bottom of the vertical shaft to receive the weight; a control box housing control and communications equipment; an energy source coupled to the control box to supply power; and at least one accelerometer positioned to record seismic source characteristics upon the weight's impact. In some embodiments, the seismic source system may be configured to operate autonomously and may be configured to communicate with a monitoring network for performance assessment.
