Thunder and lightening often trouble field seismic exploration and sometimes damage exploration instru- ments.To solve the problem,besides trying to avoid construction in thundering days or seasons,it is very important to strengthen thunder and lightening protection of the seismic recording system.Firstly,employ screened transmit- ting cable.Secondly,lay stress on screened data acquisition station from thunder and lightening.Thirdly,ensure good ground connection of data acquisition equipment.And lastly,install temporary lightening arresters in construc- tion location if permitted.
