The earthquake and tsunami that hit Chile on Sunday 28 February are reminders of the harshness of nature and the need for governments, emergency services and relief agencies to plan for natural disasters, says an expert in disaster management from Charles Sturt University (CSU). Mr Ian Manock, lecturer in emergency management at CSU’s Australian Graduate School of Policing, said that with a burgeoning world population and in spite of increasing technology, research shows that the incidence of damage to facilities and harm to people from the impact of natural and technological hazards is increasing exponentially. He said the disaster will no doubt have emergency service agencies in Chile pushed beyond their limits and the international community will be called on to assist.
