There's one itty-bitty problem on the theoretical side, again going back to John Rundle's work. His modelling suggests that the effect of a triggering event is dependent on the time to failure of the triggered event. The nearer the triggered event is to failure anyway, the bigger the impact.

This means that in cases of low seismicity areas, it can't be the case that an event has suddenly been brought forward years or months, but only days or hours. In other words, you would have seen it soon anyway, and the fact it occurred in Texas is neither here nor there.
