April 4th, 2012
Homework 1 Essay For the purpose of this paper I chose to summarize two articles from the given selection. I have chosen to read an article by Robin Spence titled “Risk and regulation: can improved government action reduce the impacts of natural disasters?”, and another by Huadong Guo titled “Understanding global natural disasters and the role of earth observation”.
ARTICLE 1 “Natural disasters have become major threats to human life and the world economy,
Governments and international organizations are cooperating to promote global and regional risk management, and to improve the capability to mitigate the effects of disasters.(Guo, 2011)” Huadong Guo wrote his article based on the

Develop a regulation towards assessment and strengthening or modifying existing buildings that are now known to constitute a potential danger 3. And to look at ways in which regulations for the provision and control of natural hazards insurance is being mitigation.
The article written by Robin Spence starts out explaining how the risk of natural hazards has highly increased over the last century. Richer countries have developed ways to decrease the loss of life from earthquake situations and also made “modest” progress in reducing casualties in storm and flood related events. Poor countries have seem to make progress as well in combating the loss of life due to earthquakes however they have not been as fortunate combating the loss of life in storms and other hazardous situations. The article asks “Why, when scientific understanding of the causes of these events is increasing rapidly and engineering skill to design against them is so highly developed, do these large death tolls continue and the financial losses continue to mount? And what should nations, cities, employees, families, for example, be doing about it? (Spence, 2011)”
Building codes and regulations today exist almost everywhere and are almost universal from one location to the next. It has been proven that through the use of regulation and codes that there has been much success in preventing and limiting damage in extreme events. “The first design code for new buildings, with an
The limits of disturbance (building envelope) and construction ingress/egress should be identified with care given to restrict disturbance, to the fullest extent practicable, to areas outside of the
2. Aren’t there policies that already insure the structure of buildings? In California, there are significant building codes already in place, but other places do not. According to
natural disasters). Gallup et al. (2003, pp.41, 46) have estimated that natural disasters in Latin America over the last 30 years have cost up to $3.3 billion and in extreme disasters costs can reach 10 per cent of a country’s GDP. This, coupled with the fact that they suffer regularly from natural disasters due to their location, means that they find it harder to recover from them. The destruction of crops causes vast economic loss which cannot be regained as farmers rely on monoculture. Furthermore, many buildings in developing countries are often built from weak materials which causes mass destruction and costly re-construction which these countries cannot afford.
Intro –What is a hazard? - Human and Physical Factors – How to manage with events
Natural disasters are the catastrophes cause by “Mother Nature”, which is often difficult to forecast or manage (Morrison, et al 2014). Examples of
A natural disaster has the capability to cause large scale damage and destruction to an area. Seismic events have been known to alter landscapes and affect the livelihoods, health and development of communities. No two earthquake events are the same and the level of threat posed by an earthquake can vary due to both the human and physical factors of an area. The 2010 magnitude - 7.0 earthquake that occurred in Haiti is an example of where a natural disaster caused a previously vulnerable area to suffer tremendous loss and debilitating socio-economic impacts, to an already poverty-stricken nation.
Further, analyze and understand the adequacy of the measures taken to adapt future climate change induced hazard risks. I have developed my capacity by doing the Masters’ Degrees in Disaster Management and Emergency Management with a research work.
While natural disasters such as floods, drought and hurricanes are commonly thought to occur due to environmental forces such as weather, climate and tectonic movements; a deeper investigation into the ‘disaster’ displays other contributing forces. Human factors have a large, if not equal, contribution to the occurrance and outcome of such disasters (Pelling, 2001). As Pelling (2001) argues, there is both a physical and human dimension to ‘natural disasters’. The extent to which the natural occurrence of a physical process, such as a flood or earthquake, impacts on society is constructed by that society, creating a ‘disaster’ as measured by a
The natural environment is, of course, not “getting its revenge”. Geophysical, meteorological, and hydrologic processes are unfolding as they have for millennia, beginning long before humans occupied the earth and continuing to the present. Given the eons-long perspective of the natural environment, it would be very difficult to identify meaningful changes in event frequency for the short time period in which scientific records are available on geological, meteorological, and hydrological phenomena. Event frequency, from an emergency management perspective, is not really the issue. It is certainly true that, over the years, more people have been affected by natural disasters and losses are becoming progressively greater. The significant feature driving these observations, however, is the extent of human encroachment into hazard prone areas. With increasing population density and changing land use patterns, more people are exposed to natural hazards and consequently our accumulated human and economic losses are increasing. Much of this exposure is a matter of choice. Sometimes people choose hazardous places, building houses on picturesque cliffs, on mountain slopes, in floodplains, near beautiful volcanoes, or along seismic faults. Sometimes people choose hazardous building materials that fail under extreme environmental stresses—for example, unreinforced masonry construction in seismically active areas. Some exposure results from constrained choices; the cheap land or
Both human and economic cost of global hazards are increasing over time due to one reason, this reason is that global hazards are more frequent in the present day. Global hazards can be split into to groups hydrometeological or geophysical. Geophysical events have occurred at constant frequency throughout the ages as they are formed by tectonic or geological processes, which can’t be affected by human factors, an example of this type of event is an Earthquake or volcano. Where as on the other hand hydrometeological hazards are increasing as they are formed by hydrological or atmospheric processes, which are affected by human factors such as global warming, an example of this type of event, is a Flood or hurricane.
Risk for disasters is a part of life; emergency situations occur more frequently than many people believe. A wise person plans for the worse, and hopes for the best. After a disaster, how well a community can recover will depend largely on how well they prepared in advance. Risk management includes identifying any potential risks to a community and proactively planning to minimize the threat. Proactive organization of resources and people to respond to emergencies can mean the difference between a community’s ability to regroup and recover, and the loss of life. To better
Many times, risks faced by contractors exist at no fault of their own. That is, in some cases the contractor is bound by a design that places specific hazards on the construction site. Designers who are cognizant of and responsive to their effort on construction safety would aid in making jobsites safer for construction workers (Gambatese et al, 1997). Situations such as these led the National Institute for Occupational Safety and Health to create a safe design concept, prevention through design. Prevention
Natural disasters may be defined as natural catastrophes which cause great damage by disrupting the functioning of a society thus rendering the country incapable of coping through using its own resources as there is a need for outsider assistance in order to effectively preserve lives and the environment. Conversely, Natural hazards are natural phenomena that are potential threats to people within a society, structures or economic assets and may cause disaster. Natural disasters are inevitable and ubiquitous worldwide. Within the Caribbean, they are chiefly present in the forms of hurricanes, earthquakes, floods, droughts, and volcanoes. The great damages caused by natural disasters may be divided into three categories: social, economic
Actions taken to minimize adverse impact of disasters. These including structural measures like building of flood defences and non-structural measures like training etcetera. Public awareness related to disaster risk reduction, contribute in promoting a "culture of prevention" by changing attitudes. It revolves around civil institutions responsible to prevent disasters.
“Natural disasters have killed more than 600,000 people and left behind trillions of dollars in damages in the last two decades, the United Nations said Monday.” (Chan) Extreme weather has caused millions of casualties and extreme damages over the years, but lately there has been an increase in severe weather events. This is causing problems in the US, with the amount of tornadoes rising in tornado alley “Tennessee experienced a 67 percent increase in tornado activity in 1983-2013 compared to the 1954-1983 time period. Oklahoma experienced a nearly 35 percent decrease in tornadoes in 1983-2013 compared to 1954-1983.”
