Stress drops for injection-induced earthquakes near the Dallas-Fort Worth International Airport in the Fort Worth Basin (FWB), Texas are estimated. The mean stress drop for the Airport sequence is lower than other FWB earthquake sequences. Airport earthquake stress drops increase with radial distance from the injection point, but only over the first 1.5 km; estimates for more distant earthquakes are spatially independent, consistent with other FWB sequences. The low stress drop Airport events occurred shortly after the initiation of injection on a fault extremely close to the well, and we suggest that here we uniquely captured the initial low stress drops predicted by direct triggering of earthquake via rapid pore pressure changes.
