                         (GASBOL) was calculated by using the distributed source line 
                         transmission (DSLT) theory during several space weather events. We 
                         used geomagnetic data collected by a fluxgate magnetometer located 
                         at Sao Jose dos Campos (23.2 degrees S, 45.9 degrees W). The total 
                         corrosion rate was calculated by using the Gummow (2002) 
                         methodology and was based on the assumption of a 1 cm hole in the 
                         coating of the pipeline. The calculations were performed at the 
                         ends of pipeline where the largest {"}out-of-phase{"} pipe-to-soil 
                         potential (PSP) variations were obtained. The variations in PSP 
                         during the 17 March 2015 geomagnetic storm have led to the 
                         greatest corrosion rate of the analyzed events. All the space 
                         weather events evaluated with high terminating impedance may have 
                         contributed to increases in the corrosion process. The applied 
                         technique can be used to evaluate the corrosion rate due to the 
                         high telluric activity associated with the geomagnetic storms at 
                         specific locations.",
