I wonder that, too. My master's thesis in engineering geology was on debris flows, which is what this was. It is fairly easy to anticipate your standard debris flow. In fact, I looked on google earth at the area where this happened, and the hillsides are riddled with narrow debris flow scars. But this massive failure was entirely different. Probably not so easy, and maybe even impossible, to predict.
