Some Thoughts on the Problems of Modelling and Simulations of Large Scale Natural Events

Large scale natural events are relatively rare, have a large to massive impact locally and globally over short or long time periods. They may have enormous consequences for the survival of the human race. They can be due to natural or human causes. This paper addresses some of the major causes and considers how modelling and simulation may be used to minimize their effects and raises validation and verification issues for such models.
