Natural Hazards

A natural hazard is a naturally occurring threat or event that will have a negative effect on people or on the environment. Many naturally hazardous events are interconnected. For example, drought can lead to famine or population displacement. There are many different types of natural hazards as well. These can include avalanches, earthquakes, sinkholes, volcanic eruptions, blizzards, droughts, hailstorms, tornados, and diseases. These events can cause large numbers of deaths, as well as property damage.

To help deal with natural hazards, the United Nations launched the International Early Warning Program in January of 2005. This program was designed to create a global warming system which can help build community resilience in the event of a natural hazard. Disaster risk reduction is critical to the sustainable development of communities. Natural disasters can cause millions of dollars in property damage and this is a major financial burden for communities.

Different regions of the Earth are more susceptible than others to particular types of hazardous events. Regions that lie on a fault line are more likely to experience an earthquake or a volcanic eruption. This happens by the convergence and divergence of tectonic plates. Furthermore, a northern region by the mountains is more susceptible to avalanches. This occurs due to the buildup of snow on unsteady surfaces.

Flood Disaster Mitigation

Describe mitigation measures that have been implemented to address the disaster that you selected for your country. Identify and briefly describe at least one additional measure that has not been implemented but would mitigate against your selected disaster. Evaluate this mitigation strategy using the FEMA criteria

Mitigation is action taken to eliminate or reduce the impact of hazards which exist within a community. What mitigation measures would you recommend for your community? Describe the topology, types of hazards. A natural disaster? A potential man-made disaster? What would you base your decisions on?

Bioterrorism Preparedness

Following criticism for its response to the 2001 anthrax attacks, the Centers for Disease Control and Prevention has placed a high priority on bioterrorism preparedness and subsequently developed a controversial Smallpox Response Plan. See http://www.bt.cdc.gov/agent/smallpox/prep/cdc-prep.asp Why is this plan controversi

You have been given the responsibility to oversee the implementation of the Incident Command System for the disaster. Address the following: Briefly describe the key features of an incident command system and provide specific examples of how

Exploration Risk in Oil Production

Please read the class notes and the referenced article to help in answering the questions. Please use per reviewed articles (see attachments). Think about who should assume the exploration risk in an oil production sharing agreement. In your discussion posting, be sure to address the following points: How has this week's m

Geologic Disaster and Hazards

Choose one of the following geologic hazards: earthquake, landslide, or flood. Assess the factors that influence the occurrence of your chosen hazard. Analyze the human role in elevating the risks of occurrence, as well as mitigation strategies to minimize damage and loss of life.

Geologic Time

Research one of the Periods in the Mesozoic and research one of the Periods in the Palaeozoic. Discuss when and why it occurred and describe three unique events that happened during that time.

Faults Foci and Epicenters

How are faults, foci (plural of focus), and epicenters related? Faults that are experiencing no active creep (relatively consistent yet minor movements) may be considered "safe." Rebut or defend this statement with what you have learned so far about faults.

Hurricanes and Coastal Areas

Please help with the following natural hazard related problem. What is the major danger of hurricanes to coastal areas and how has the federal government historically responded? Explain the answer to your solution.

Green Light System: Mitigating Disaster Scenarios

Apply the Green Light System to a disaster scenario of your choice and describe how it would be used to manage the crisis. You can pick a real-life disaster, such as Katrina or 9/11, a personal disaster from your own life (your car breaking down in the middle of nowhere, for example), or a fictional scenario such as a zombie apo

Continental Drift

Give examples of geographic facts that supports the ‘continental drift’ theory. (a) Scientists in contemporary times acknowledge that the continents have shifted, but were skeptical when Wegener first proposed the theory. What has changed? (b) How does the continental drift theory utilize the scientific method/theory

Emergency Management Process

Explain the processes of transitioning from emergency management planning into action. What are the key elements of ensuring a smooth transition? What are potential barriers between planning and action?

Tectonic Plates

How does the motion of the tectonic plates affect the climate? How does the motion of the tectonic plates affect the geography? How does the motion of the tectonic plates affect the distribution of organisms?

Volcanoes and Earthquakes

I need help with the following questions; How do different categories of volcanoes form? What is an earthquake? What causes earthquakes? Why is most of the volcanic activity in the United States located in the Pacific Northwest region?

The solutions explains about the destructive flooding in the Midwest during 2008. US Geological survey had conducted a study and found certain anomalies in the atmosphere and soil moisture in North America. The increasing moisture flow from the south and the drought across the South eastern United States proves the theory of the moving Atlantic subtropical ridge called the "Bermuda High."

The solution describes the following points 1. There was a Midwest flooding causing great destruction in 2008 which can be compared with the flooding of 1993 2. Study of climate and weather patterns during 1993 revealed large scale circulatory anomalies in the atmosphere or soil moisture in all parts of North America 3.

Exxon Valdez Oil Spill

The Exxon Valdez oil spill: explain the history of the event including how the situation reached a crisis point. Document as many sides of the situation as possible and include the resolution, if any was reached, of the crisis. If there was no resolution, speculate on how the crisis may be resolved in the future.

Michigan: Environmental Imbalances

When pressures and temperatures become unbalanced in the Earth's atmosphere, it can produce some dramatic effects as the system tries to rebalance itself, or re-equilibrate (i.e. reach equilibrium). Many of these changes are things that, on a small scale, we are used to witnessing every day in the form of weather, such as wind,
