A comparative study between GASBUGGY and GNOME data shows considerable differences in observed travel times, amplitudes, and in the excitation of surface waves. The Pn and P arrivals from GASBUGGY follow the Jeffreys-Bullen curve closely, whereas the arrival times for GNOME were early to the east and late to the west. Relatively higher amplitudes of phases associated with Pg and Lg were recorded to the east of GASBUGGY, whereas Pn and P and surface waves LR recorded higher amplitudes to the west of GASBUGGY. A refinement of the GASBUGGY location was attempted by adjusting the arrival times relative to the residuals observed from GNOME. The maximum epicentral error increased approximately 7 kilometers to the north and 22 kilometers to the west.
