Colonization: Haiti "Two hundred years ago‚ our precursors in Haiti struck a blow for freedom‚ which was heard around the world‚ and across centuries." – Baldwin Spencer The Legacy of Colonization It is true that the effects of colonization‚ or the establishment‚ maintenance‚ and domination over a nation and its people‚ thus creating a political and economic domination and dependency between the colonizer and the colony‚ are in fact still felt centuries later in present day Haiti. This is the

INTRODUCTION A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include floods‚ severe weather‚volcanic eruptions‚ earthquakes‚ and other geologic processes. A natural disaster can cause loss of life or property damage‚ and typically leaves some economic damage in its wake‚ the severity of which depends on the affected population’s resilience‚ or ability to recover.[1] An adverse event will not rise to the level of a disaster if it occurs in an area

CHAPTER 4 Role of the Navy in Disaster Management in Sri Lanka The role of the Navy is clearly defined in the Navy Act (1950). This chapter describes the more general roles pertinent to the seaward defence of the island nation and the Aid to civil power activities. The views of the three focus groups selected for data collection are discussed in detail. A critical analysis is carried out in qualitative terms regards to the actual disaster management system that exists in the country and the

These disasters occur in form of drought‚ desertification‚ flooding‚ epidemics‚ coastal erosion‚ dam failure‚ building collapse‚ oil spillage‚ maritime collision or accident‚ bomb explosion‚ communal clash‚ fire‚ air crashes and boat mishap‚ amongst others.

Earth Science 1 October 29‚ 2012 Homework Assignment 1. Explain how you should react or what you should do when you feel an earthquake if you find yourself in each of the following scenarios. Do not exceed the space provided. a) Indoors: I will stay calm and drop to the ground. I will take cover by getting under a sturdy table or other piece of furniture. I will hold on until the shaking stops. If there isn’t a table or desk near me

The short answer is that earthquakes are caused by faulting‚ a sudden lateral or vertical movement of rock along a rupture (break) surface. Here’s the longer answer: The surface of the Earth is in continuous slow motion. This is plate tectonics--the motion of immense rigid plates at the surface of the Earth in response to flow of rock within the Earth. The plates cover the entire surface of the globe. Since they are all moving they rub against each other in some places (like the San Andreas

These Seismic waves are what cause the intense shaking at the Earth’s surface that can cause buildings and roads to collapse. All across the world governments are going to great lengths to ensure the safety of their citizens by building resistant structures that are designed to withstand earthquakes and prevent the immense damage their shock waves do.

Before the earthquake‚ Haiti was already a country with high prevalence of infant mortality‚ poor nutrition‚ and diseases such as HIV and Turberclosis. In Haiti ‚“An estimated 87 of every 1‚000 children born die by the age of 5 years‚ and >25% of surviving children experience chronic undernutrition or stunted growth. Maternal mortality rate is 630 per 100‚000 live births.” (SITE) The life expectancy in Haiti is 61 years. Due to low vaccination rates‚ Haitians are at risk of spreading vaccine preventable
