Among W. Geographic Information Systems and Science.

Among the variety of problems that disturb people, it is not always easy to define one particular problem and prove that it is the only one that deserves people’s attention.

Problems connected to nature and human impact on it is considered to be a burning aspect to deal for a long period of time. “As the world population grows, so more people are exposed to hazard” (Smith 3); this is why the decision to choose environmental hazards as the topic for this GIS project is not accidental.

Study Objectives

The main purposes of the study are the evaluation of environmental hazards, analysis of the historical facts, and development of the ideas on how to prevent some hazards in future or, at least, get prepared for possible damages. People awareness about the possibility of natural hazards turns out to be not enough; and the process of mapping hazards and identification of the places which are in danger.

Literature Review

It is known that solving problems during the GIS project “involves several distinct components and stages” (Longley et al. 15); this is why it very important to define one purpose to be achieved during the analysis and several supporting ideas on how to comprehend the importance of hazards’ evaluation. The results of numerous investigations on different levels show that “it is impossible to live in a totally risk-free environment” (Smith 4); however, there is always an opportunity to examine what threats are waiting for people in future and the ways of how these threats may be overcome or minimized by means of human actions.


The current study is based on the evaluation of the particular territory and the analysis of the data given online. The ideas offered by the National Institute of Environmental Health Sciences may be used as a reliable and powerful source to define what challenges created by nature are the most serious for people. After earth conditions are taking into consideration, it is possible to rely on the census data in order to clear up what parts of North America may be changed or damaged by nature. In general, the use of different methods that depend on weather conditions and population level seems to be the most adequate for this type of work.

Planned Analysis

A thorough evaluation of conditions that may influence the development of environmental hazards is the central point in this work. The analysis of information found has to be divided into several logically arranged steps: earth analysis, population, human effects on nature, and possible territory for hazards.


At the end of the study, it is expected to define the most vulnerable territory and the outcomes of hazards.

It is also necessary to clear up what types of hazards are possible in the chosen territory and how serious the level of damage can be. Evaluating the already found information, it is possible to predict that the north-west of the United States of America may undergo considerable damages due to the level of population and the structure of the earth. The main point is to focus on hazards’ types and effects.


In general, the GIS analysis of environmental hazards in the USA shows that a number of dangers for people exists all the time, and people should not only be aware about these threats but also be able to take necessary precautions and be saved.
