Rolling this technology out in practice is quite challenging. How do you trigger "The Alarm" for a given area? How much of a guard band do you put around the event and what happens when you have false positives? Do you call everyone back to the region and say sorry it was a false alarm, only for it to trigger a week later! Would not want to be the one calling the shots on this. It also seems like a good technology to throw into a movie plot - Super Mega Quake... starring Dwyane Johnson.
