We noted that disaster had detrimental consequences to not only humankind but also animals and plants life. Disaster is a great threat to the development of an economy. It is catastrophic and leaves long term and short term effect once it strikes. In North Korea, a nuclear disaster that was triggered by an earthquake which later resulted in a tsunami-affected human, nature animals and agricultural activities. The disaster also resulted in economic depression affecting Chinas GDP (Plümper, Flores " Neumayer 2017). We have seen that disaster has catastrophic effects on people economic, social and political life as to the surrounding.
Disaster stroke unexpectedly when people are not prepared to control them. The level of damage must be measured and records kept for future references. This means that data must be collected. On issues of disaster management, the data collected should show the number of people and plants affected the economic and social impact on people's life. This will aid in the delivery of aids services to the affected sectors( Wex, et al ,2014). ( For accuracy of the data directs observation method of data collection would appropriate as it will give us the true image of the catastrophe that has occurred as we are able to avail ourselves in the fields of the scene (Smith, 2015). The use of the descriptive method of analyzing data was appropriate because the large volume of data to be collected when a disaster has concurred.
Population and Sample
North Korea having a larger population and fast-growing economy was largely affected by earthquakes leading to mass destruction of property due to the tsunami that arose. Plant and human life was also an endangered species.Nuclear weapons had the devastating effect on human life and animal life due to environmental pollution effects (Nakata " Sugisaki, 2015). Looking at the affected personnel's we decided to pick affected human as samples beings to help us conduct the study on disaster through random sampling because North Korea contains a large population and random sampling was be appropriate in data collection during the period of study through direct observation as a method of data collection.
Variables and Measures
The variables used in the research were nuclear weapons, tsunami, earthquakes, and tornadoes. This is also referred to as interdependent variables. Although these variables had an effect on human, animal, plant and the environmental life they had a devastating effect on natural life and to the economy of the country. The effects depend on the dependent variables and are referred to as interdependent variables (Wildemuth, 2016). The dependent variable will be measured according to the impact on the independent variable. The devastating effects of the tsunami were being measured according to the level of the tsunami that occurred.
Data Collection Methods
Due to the large population size, we decided to use direct observation method of data collection because it's unreliable to use questionnaires on parts affected by tsunami due to the displacement of people and also a risk to the researchers (De Albuquerque et al., 2015). Direct observation method of data collection will give us the true image of what should be done and because we will be in the field, will be able to collect and record first-hand information from the affected personnel (Palinkas, et al, 2015).
Data Analysis Methods
After direct observation from the affected areas, simple random sampling method will be appropriate to use in data analysis. This is because it is difficult to develop a complete list of the population, especially during such catastrophes due to the wide dispersion of people geographically due to disasters. Few people will be selected from the population for sampling to represent the whole population that is affected by a disaster. Data will, therefore, be presented and assigned numbers in order to come up with the exact information required (Taylor, Bogdan " DeVault, 2015).
