A: In the 1970s, there was an effort to map geohazards in Quebec. Seismic risks, flood plains and areas prone to rock falls, erosion and landslides were all being put on a map. But that provincial government initiative was abandoned. The instrumentation required to monitor all these hazards was too great. In addition, when you start putting georisks on a map, property values are affected.
Actually, the physics is all wrong here, but I like the statement that you can't do anything because of property values.
