A natural hazard differs from a catastrophic as well as a natural disaster. before taking this course I thought they all pretty meant the same thing but I was sadly mistaken. A Natural hazard is an event that happens natural but becomes a hazard when human life is affected or loss due to it. A Catastrophe on the other hand is a violent and tragic even that often leaves a change in a feature of the earth like Hurricane Katrina which also happened to be the most costly catastrophe in history. A natural disaster is a major event caused by the forces of nature like landslides, floods and fires.
Guyana is apart of the Caribbean Plate which is mainly a oceanic tectonic plate underlying Central America and the Caribbean Sea off the north coast of South America. The Caribbean Plate also borders the North American Plate, South American Plate, The Nazca Plate and the Cocos Plate. Of these regions are intense seismic activity, including very frequent earthquakes, volcanic eruptions, and even tsunamis. The Greenstone belts of northern Guyana which were formed by volcanoes on the oceanic crust, between 2.3 and 2.2 billion years ago, over a span of over 100 million years ago became part of a large mountain range caused by the pressure of convergent tectonic plates.

Hi Anthony,
ReplyDeleteGood luck with your blog on Guyana. I look forward to learning more about the natural disasters and catastrophes that have impacted the country.
Great first entry. Looking forward to all you'll discover about Guyana's natural hazards with us...
