Natural Disasters and Their Impacts

Natural disasters and their impact on natural risk are increasing, and hurricanes and floods are expected to increase due to global climate change. At present, about 4 million people lose their homes every year due to natural disasters, and 128,000 people die worldwide without taking into account the damage caused in the process and the cost of the world economy. Every year developing countries are suffering $ 35 billion from natural disasters in other parts of the world.

Disasters may occur if extreme events exceed the ability of the community to handle events. Understanding the process by which natural disasters affect local communities is important for four reasons. First, we need information from the process to determine the situation before we make the community vulnerable to disasters. Second, you can use information on the disaster impact process to identify specific parts of each community that are unduly affected (low income households, minority ethnic groups, specific type of business, etc.). Third, information on disaster impact processes can be used to determine event-specific conditions that determine the extent of the disaster. Fourth, by understanding the disaster impact process, the planner can identify the appropriate emergency management intervention. Second, the physical impact and emergency disaster recovery combine to create a social impact of disaster.

Currently, it is possible to predict most natural disasters and minimize their impact, but in the last decades there has been a significant social impact. In this article, the natural disasters, including those caused by geological factors and infectious organisms, is defined as adversely affect the natural phenomenon in human society. - Are you part of a natural disaster? With the help of advanced technology, most natural disasters can be predicted, but in general, natural miracles will occur unexpectedly. Most people do not know what to do before, during, and after devastating events. The most common questions are what it is, where it happens, when it happens, and who will be affected.

Natural disasters occur naturally without being influenced by humans. Human disasters are events that are influenced by human activities and have a great impact on humans and the environment. Natural disasters can not be changed or mitigated in any way due to the nature of the disaster. One factor that supports this is the severity of the earthquake. For example. The Richter scale of the 2011 Haiti earthquake was 7.2. And Japan is huge ... mitigating natural disasters is a revolutionary activity. However, the flow of technology, such as the difficulty of obtaining appropriate raw data, the lack of an effective graphical user interface, the complexity of the predictive model, and the cost of digitization, are still hindered by many problems Carrara et al., 1999).
