m chịu bài này r, giúp m đi Think about a natural disaster and write about its effects. Some suggestions: What is the definition of the disaster? What are the effects of the disaster (at least 2 effects)? How do people prepare for the disaster? (at least 2 ways of preparation)

Disasters can be classified as natural disasters, technological disasters, or complex emergencies. The latter include civil wars and conflicts. These classifications are arbitrary and refer to the immediate trigger-natural phenomenon or hazard (biological, geological, or climatic); a technologically originated problem; or a conflict. In reality, all disasters are complex events stemming from the interaction of external phenomena and the vulnerability of man and society.A public health approach to disaster risk management will aim to decrease the vulnerability by adopting prevention and mitigation measures to reduce the physical impact and to increase the coping capacity and preparedness of the health sector and community, in addition to providing traditional emergency care (response) once the disaster has occurred.
