Discuss the view that the impact of earthquake hazards depends primarily on human factors (40 marks). It is impossible for anybody to argue that human factors do not have an effect on the impact caused by earthquake hazards; however the extent of the effect is debatable depending on the situation. This can depend on many different aspects‚ for instance the level of development in the relevant country‚ the standard of infrastructure‚ the magnitude and location of the quake and lastly what time

Environmental Hazards The Four Categories of Human Environmental Hazards There are many exposures to hazards in our environment today that brings along the risk of an injury‚ different types of diseases‚ and even in some cases death. These hazards are called human environmental hazards. There are four categories to human environmental hazards which we will discover and discuss further in detail and they consist of cultural hazards‚ biological hazards‚ physical hazards‚ and chemical hazards (Wright &

Course Title IEQ-05 : Earthquake Geology and Geoinformatics (Dept. of Earthquake Engineering‚ IIT Roorkee) What is an earthquake? An earthquake is the vibration of the earth produced by the quick release of energy. Most often‚ earthquakes are caused by movement along large fractures in the earth’s crust. Such fractures are called faults. The energy that is released radiates in all directions from its origin in the form of waves. These waves are similar to the waves that occur when you drop a

Figure 5.19 The mortar in unreinforced masonry walls such as these in Iran‚1990(A) can easily fail during an earthquake. Oftentimes the entire structure crumbles‚ leaving a pile of rubble in which survive. Shown in(B) is one of the many masonry homes to collapse during the 1988 Armenia earthquake (M6.9)‚ claiming nearly 25‚000 lives. The failure is called soft-story collapse. Soft-story collapse is a common problem in commercial building where the first floor has considerable open space for

Natural Hazards What is a natural hazard? A natural hazard is a naturally occuring physical event which poses a threat and negatively impacts people and the environment. Examples of natural hazards are: earthquakes‚ tsunamis‚ wildfires‚ floods‚ volcanic eruptions etc. Earthquakes and their Occurence What is an Earthquake? An earthquake is a sudden rapid vibration along the earth’s crust due to individual tremors‚ sometimes causing great destruction to the earth’s lithosphere and its inhabitants

PART I INTRODUCTION AIM The aim of this report is to describe the Newcastle earthquake and identify its social‚ physical and economic effects on the community. The event in detail‚ major effects‚ how the event was caused‚ the effects on the communities property‚ people‚ infrastructure and economy‚ will all be addressed in this report. Also the long term planning implications‚ preventative measures‚ preparedness‚ response implications‚ and well as recovery implications will covered and described

Natural Hazards and Natural Disasters A natural hazard is a threat of a naturally occurring event will have a negative effect on humans. This negative effect is what we call a natural disaster. In other words when the hazardous threat actually happens and harms humans‚ we call the event a natural disaster. Natural Hazards (and the resulting disasters) are the result of naturally occurring processes that have operated throughout Earth’s history. Effects of Hazards Hazardous process of all

Earthquakes and Logarithms Earthquakes are responsible for a wast majority of natural hazards on our planet. This natural geological phenomena are almost impossible to predict‚ and they occur usually in zones of the planet that are prone to movement in the uppermost crust of the earth. Certain areas are more likely to experience earthquakes‚ and also the aftermath of the earthquakes can be just as destructive or sometimes even more. Different methods of measuring earthquakes have been implemented
