* The shaking starts from the focus and spreads out. You can get an idea of how this happens by throwing a pebble into a pond. See the ripples that move out in circles? The vibrations from the focus are something like that. * The vibrations are more properly called seismic waves. As seismic waves travel through the body of the Earth, they behave in different ways, depending on what they encounter ...

Natural Hazards and Disasters

Risk and vulnerability can sometimes be reduced if there is an adequate means of predicting a hazardous event.  Volcanic eruptions are usually preceded by a sudden increase in the number of earthquakes immediately below the volcano and changes in the chemical composition of the gases emitted from a volcanic vent. If these are closely monitored, volcanic eruptions can be often be predicted with re...

Earthquake in Japan

The tsunami waves overtopped seawalls and destroyed diesel backup power systems, leading to severe problems such as large explosions and radioactive leakage. It has been almost a year since the devastating 9.0 earthquake and tsunami destroyed coastal communities in northern Japan killing more than 15,000 people. What struck me the most about this tragedy is the reaction of the Japanese community a...

Causes and Effects of Earthquakes

Earthquakes can mainly have two dreadful effects. First, one direct effect of earthquakes is ground shaking and landslides. The earthquake’s waves make the ground move, shaking buildings and causing weaker structures to collapse. The damage of properties can lead to secondary effects such as fire, which is produced because of the rupture of natural gas mains and water lines. Second, other post-e...

The effect of earthquake

Apart from psychological disorders, damaging to buildings can certainly result from the earthquakes. Non-durable buildings may be destroyed because of concussion of the earthquake. Thus, most of the people can lose their own homeland when they are facing the earthquake. As it is very clear seen, damaging to buildings is directly proportional with earthquakes. At last, it is an obviou...

The Impact of Earthquake Hazards

It is difficult to argue convincingly that the impact of human hazards depends primarily on human factors as in every case there are always numerous factors that contribute to the extent of the earthquake. The easy route would be to argue that less developed countries are impacted more seriously by earthquakes due to human factors such as poorly built infrastructure and high population densities h...

Plate Tectonics

Scientists presume this is the fault that most likely ruptured because it is closest to the epicenter of the rupture. Although this was a big catastrophe for human life on the island of Haiti, it was not really unusual given the plate tectonic activity in that area. Unfortunately for Haiti, it is one of the most poorest and underdeveloped countries in the world. Its government was not really in th...

Overall, the city of San Francisco, and surrounding cities, would all suffe...

Tectonic Hazard Profiles and Natural Disasters

Countries such as Japan who have both of these have to be well educated in responding to hazards and are lucky enough to have the technology in order to predict. It could also depend on whether the location is mountainous or flat as far as volcanoes are concerned. Hazards in mountainous areas are likely to be easier to respond to quicker than in flat areas as you can see what’s happening from af...

Dynamics San Andreas Reflection

As the movie goes, it never failed to entertain us. Also the stories of the characters featured in the movie were really interesting. If I were to put myself in the situation they were in, I might have a very low chance of surviving the disaster. I wouldn’t want to experience the type of catastrophe shown in the movie as well. Maybe the least thing I can do is to be prepared because I know we ca...

Fire: A rapid, persistent chemical change that releases heat and light and is accompanied by flame, especially the exothermic oxidation of a combustible substance. Drought:A drought is a long period of very dry weather. It is a long time with little or no rain. Not all natural disasters can be prevented. Each natural disaster has its own factors and complications. Understanding the basic principle...

Convection Currents and Earthquakes

The earth's crust I s made up of sections called plates. These sections 'float' on the liquid mantle and slowly move around. The movement of the plates is caused by convection currents. A convection current is how a liquid moves when it is heated. Hot liquid rises up and pushes the cooler liquid out of the way. In the mantle, this is happening all the time. As the liquid rock moves, it can push th...

Geologic Hazards And Disasters

Most people are also caught up in the debris and so they suffocate due to lack of oxygen.

Disasters can take many different forms and the duration can

According to Wills, (2009) generally, in some respects natural disasters may have a greater impact on more economically developed countries. For example, higher levels of infrastructure can be found in more economically developed countries, which is costly to mend if damage occurs. It may also be that although more economically developed counties are more able to cope with natural disasters than l...
