Some Recent Major Events and Considerations for Modelling and Simulation

Abstract

Large scale natural events are relatively rare,have a large to massive impact locally and globally overshort or long time periods. They may have enormousconsequences for the survival of the human race. Theycan be due to natural or human causes. This paperaddresses some of the major causes and considers howmodelling and simulation may be used to minimize theireffects and raises validation and verification issues forsuch models.
