The invention of Richter scale has enabled us for computing the magnitude of earthquakes. Today, it is possible to identify frequently earthquake occurring places and the intensity of every earthquake. Modern facilities such as earthquake alarming systems are some of the advancements in this area. However, lack of improved infrastructural deterrence techniques often affects the effectiveness of disaster prevention in mage cities. According to census reports published by Government of Maharashtra (2000) in 1991, 60% of the registered buildings in Mumbai were made up of non-engineered materials such as informal masonry. It is important to note that Mumbai is categorized under seismic zone 3, which indicates the high vulnerability to the occurrence of devastating earthquakes. The earthquake history of Mumbai reflects that large number of earthquakes occurred across different parts of the city during the last century and even in the last two years. Severe losses had not been reported until 1967 when one attacked Koyna region of Mumbai with a magnitude of 6.3. Large number of buildings was destroyed at this calamity. Damages of such sorts can be avoided to a large extent only if the city employs geotechnical guidelines for the disaster prevention.
The Earthquakes and Megacities Initiative (EMI) reports that “poor governance structures, lack of awareness, and poor professional standards and ethics” are some of the major impediments for disaster prevention in mega cities (cited in Wenzel, 2006). ...Download file to see next pagesRead More

They are earth tremors that result from the shifting and shaking of the rocks beneath the earth’s surface, releasing energy that has been build up over long periods. This paper gives an explanation of the formation, occurrences, causes, and how an earthquake forms through the tectonic plate theory. The crust and the uppermost part of the mantle are made up the tectonic plates that float over the molten rocks. The plates are in a continuous motion and move over and under each other colliding at each other, which can result in a...

I fully disagree with the use of levees to protect flood prone areas. This is because; regardless of a strong network of levees Hurricane Katrina smashed it down.

...should have a wide scope of coverage; they should be applicable to as many situations as possible. A good plan should identify possible sources of emergencies and their associated counteractive measures (Martin, 2006). Emergency mitigation plans should be sensitive to the available resources. It should recognize the financial capability of a particular region. A good mitigation should be able to respond rapidly. An emergency planner should carry out a survey of Tampa region to assess the required measures in an emergency mitigation plan. There are successful mitigation plans in other parts of the world that a planner can use (Martin, 2006). Some of the successful plans...
