One question I would ask Susan Murphy is what do you expect a person to do if they are in an area that is at risk for an earthquake. For example, I am in California and we have been told for decades that we are at risk for a large earthquake. However, I do not know anyone who actively changes their daily life in response to this risk. Would you suggest moving out of an at risk location of an earthquake, even if the dangers are relatively uncertain? It is difficult to imagine anyone moving homes in response to a potential earthquake risk that is still uncertain and may never occur. I think it is more likely that instead of people moving away from their hometown, that they take active measures to protect themselves from the risk of an earthquake, such as creating more sturdy buildings that will fare better in the event of an earthquake.
