Erosional processes, including flooding, landslides, and windstorms replenishes soil and.Which which direct water to flow downhill to form rivers and lakes. Earthquakes are one of the processes responsible for the formation of mountain ranges.Present on the Earth's surface, and for producing the atmosphere. Throughout Earth history, volcanism has been responsible for producing much of the water.They are responsible for things that make the Earth a habitable planet for life. Such processes are beneficial to us as humans because How can each type of disaster be predicted and/or mitigated?Īs discussed before, natural disasters are produced by processes that have been.How often do these hazards develop into disasters?.What scientific principles govern the processes responsible for the disasters?.Where is each type of hazard likely to be present and why?.Some of the questions we hope to answer for each possible natural disaster are:.Such as oil and toxic material spills, pollution, massive automobile or train wrecks,Īirplane crashes, and human induced explosions, are considered technological disasters,Īnd will not be considered in this course, except when they occur as a secondary result of a natural disaster. Poor levee design results in a flood), other disasters that are directly generated by humans, Although humans can sometimes influence natural disasters (for example when.Minimization of risk is called hazard mitigation. Then, we can develop an action to take to minimize the risk. Something about the processes that operate, and understand the energy required for the Hazard to humans, and thus minimize the risk. The risk from natural hazards, while it cannot beĮliminated, can, in some cases be understood in a such a way that we can minimize the Risk is characteristic of the relationship between humans and geologic processes.Point - There would be no natural disasters if it were not for humans. All of these processes have been operating throughout Earth history, but the processes haveīecome hazardous only because they negatively affect us as human beings.Among the natural hazards and possible disasters to be Hazard occurs and destroys human life or property, then a natural disaster Noticeable when they cause loss of life or property. Geologic processes effect every human on the Earth all of the time, but are most.Most hazardous process are also Geologic Processes.Natural Hazards (and the resulting disasters) are the result of naturally occurring processes that have operated throughout Earth's history. In other words when the hazardous threat actually happens and harms humans, we call the event a natural disaster. This negative effect is what we call a natural disaster. Natural Disasters & Assessing Hazards and Risk EENS 3050Ī natural hazard is a threat of a naturally occurring event will have a negative effect on humans.
