Hurricane Katrina is termed as one of the worst hurricanes of the last decade to have hit the United States. The death toll of this devastating natural disaster was more than 1500 people which itself is a horrifying figure and represents the amount of ferocity it brought with it. The flooding caused by the Hurricane consumed many lives as more than a million of families and people more than that number rendered homeless by the tenacity of the storm. The most affected areas were New Orleans and Gulf Coast. Apart from the consumption of human lives a lot of wildlife, pets and sea creatures died due to the intensity of both the hurricane and the flood. The official figures estimates Katrina to be the costliest storm in the history of Modern USA as it consumed a cost of close to $108 Billion in damages and loss of lives. The storm reached a maximum peak with wind speed touching close to 25 to 30 nautical miles per hour while at the eye of the storm wind speed was close to 75 nautical miles per hour.
I was enjoying my holidays in America and I happened to reach New Orleans three days before the storm. I have preplanned to stay at New Orleans for 6 days and would be enjoying the different tourist places, cultures, cuisines and many more such related elements. However my plans went haywire just a day before the hurricane (Barzinpou & Esmaeili, 2014). I had no idea about the emergency situation and was marketing when I noticed that the Police along with the different authorities of the town were warning the people of the impending danger and were advising them rather forcing them to completely stay inside the doors.
It was a horrifying experience for me for the next few days as I was totally devastated and for the first time felt that it was my dooms day. I watched the wrath of the storm from the hotel as well as the rescue center. I was amazed to find out that even the largest superpower of the world was helpless in front of Nature’s fury and their arrangements were just too small for tackling a hurricane like Katrina.
As Katrina made landfall, the right side of the storm, which carried the strongest winds, slammed into Gulfport and Biloxi, Mississippi, destroying both the cities. A large storm surge ranging from 10 to 28 feet devastated coastal areas across coastal Mississippi (Wex et al. 2014).
“The surge exposed engineering mistakes in the levees and floodwalls designed and built by the U.S. Army Corps of Engineers, causing extensive flooding throughout the New Orleans region,” said Sandy Rosenthal, the founder and director of the advocacy group aimed at educating people about the catastrophic flooding in New Orleans in 2005 and a known critic of the Army Corps (De et al. 2015).
A large portion of the city was under water and transportation took a toss. The airport, railway, road transport was practically absent during this time and we had to rely on rubber boats, speed boats and rafts to ferry us across some necessary places.
The National Guard was called in to help with evacuations. Thousands along with me sought refuge in the New Orleans Convention Center and the Superdome. It was one of the largest displacements of a population since the Great Depression. We all shared food and necessary items with one other and I be friend a lot of persons. However I was also feared about my return journey and told the authorities about the total fact. They helped me in a great deal to be able to fly out to the airport. According to The Information Center, a neutral research organization in New Orleans, the storm removed more than 1 million people in the Gulf Coast region (Achir & Hamid, 2015).
The Sandy Hook Shooting was one of the worst cases of school shooting that took place in USA. Some of the main conclusions that can be formed after such a massive incident are;
Actions by school personnel saved many lives-The promptness of school personnel saved many lives. In spite of the huge loss of lives many school children were alive just because of the promptness and activeness of the school personnel.
Lockdown procedures must be implemented as early as possible- The value of the lockdown concept was highlighted in this particular case. The lockdown system helped to save the life of many occupants in the school (Van De Walle, Turoff & Hiltz, 2014).
Importance of training the school staff- The school staff must be trained and empowered to act in any kinds of situations and other necessary emergency facilities. The training imparted to the school staff thus will help them to be more active and efficient.
Both the shape and size of the earthquake determine whether or not a tsunami forms from the transfer of pressure that happens when the earth moves, but let’s assume the earthquake is of the right size and shape so that a tsunami is formed (Wattegama, 2014). One of the key differences between the analogy of the car being raised by a mechanic’s jack and the tsunami is that the distances are millions of times further in a tsunami than in the space under a car. Instead of the pressure being transferred a few inches, the tsunami travels for many miles, sometimes even a thousand miles or more. But because water cannot be compressed, the pressure passes very quickly from atom to atom in the water. The tsunami can cross an ocean at travelling at hundreds of miles an hour. But remember that an ocean wave is an up and down movement of the water, not, as it appears to us on shore, millions of tons of water moving forward like it was being pushed by a bulldozer or a train with a snowplow ahead of the engine. The tsunami is often only a meter or two in height as it crosses the ocean (but at tremendous speed).
Now this up and down movement of water (with the pressure behind it), a wave, starts to reach a point where the water is (relatively) rapidly getting shallower. A good deal of the force that was raising the water into a wave now finds less and less water to move, so the height of the wave rapidly increases (Wattegama, 2014). It can be a hundred feet tall or more by the time it reaches the shore. In order for it to “find” enough water into which it will transfer the force (remember, some of the force [energy] was used all along the path of the tsunami to move all those water molecules up and down) water is drawn away from the shore which compensates for the deep water that is no longer there to continue to transfer the pressure of the wave. This water, too, adds to the height of the tsunami wave.
The primary and only really effective precaution one can take to avoid damage from a tsunami is to place your building (home or office) as far from the shore as possible, and at as high as possible an elevation about sea level. Tsunamis have been known to travel inland for more than a mile, and if the land is very flat, it could be far more than that. Now, that is not to say that the wave of the tsunami has traveled that far from the shore but the water from the tsunami wave can be so huge and amount that it can flood land for several miles inland. Pictures taken from the air showing the flooding are a good indication of what those can be. Phuket also experienced devastation that reached far inland, but not as much flooding (Schwab, Sandler & Brower, 2016).
