Abstract
A lightning protection system is disclosed for a seismic data acquisition system having single or multiple geophones positioned at predetermined ground locations over a large area. A surge suppressor is placed across the leads to which the geophones strings are connected. Such surge suppressor preferably comprises a gas discharge arc tube. The base or spike of each geophone is implanted in the ground, A ground lead is connected to the surge suppressor. Electrical energy from a lightning strike affecting the geophones, cables, data acquisition boxes, etc. is dissipated by the surge suppressors through the multiple spikes to the earth thereby to minimize damage resulting from lightning.
