Almost every time after a large earthquake occurring near a residential area questions are raised in the media as to "why the event was not anticipated?". The argument is that a successful forecast would reduce loss of life, if not necessarily economic damage, by allowing the evacuation of dangerous buildings, the clearing of tsunami-prone coastal...
