Winds range from 110 to 205 mph. c. Violent tornadoes 1. Represent only 2% of all tornadoes. 2. Winds exceed 205 mph.
The southern part of the USA is where a lot of tornadoes occur , to be precise more that 1,200 tornadoes and most of these are in the southern parts which mainly experience many of either F4 or F5 tornadoes annually . Tornadoes are a weather phenomenon that occur regularly throughout the US. They are caused by very low pressure systems that form during storm events. Signs of Tornadoes include unusual amounts of heavy rain and hail , A large, dark, low-lying cloud (particularly if rotating) and Dark, often greenish sky. These indicate the awareness of shelter and too be ready to take cover if needed.
In Mexico City of 1985 and San Francisco of 1989 there were big earthquakes. Many people died and may buildings were destroyed. About 100,000 people were killed and over 300,000 buildings were destroyed or damaged. Both of these Earthquakes were quite similar. The 1985 Mexico City earthquake was one of the most devastating earthquakes in the history of the Americas.
“The 7.0-magnitude earthquake would be a strong, potentially destructive earthquake anywhere, but it is an unusually strong event for Haiti, with even more potential destructive impact because of the weak infrastructure of the impoverished nation” (Thompson, 2010, p.1). There were more than 40
(i) Description of Disasters: Hurricane Katrina is said to have been the most costly and deadliest hurricanes in U.S history, resulting in $81.2 billion dollars in damage and 1836 casualties6. The hurricane made landfall in New Orleans in the early morning of August 29th, 2005 as a Category 3 or 4 storm. The heavy rains that were produced as the hurricane moved inland, along with the poorly designed levees, caused all 56 levees in New Orleans to fail, resulting in freshwater flooding of 80% of the city15. Hurricane Katrina devastated an area over 160 km from the storm’s eye, which included parts of Mississippi, Alabama, Florida and most importantly, Louisiana6. It originally formed off the Bahamas, on August 23rd, as a Tropical Depression and strengthened to a Category 1 storm once it made landfall in Florida on August 25th.
They are both convection storms, which means rising air causes low pressure and, in turn, makes air rush in from surrounding areas to create very strong winds. However, the area that each storm covers differs drastically. A hurricane can cover up to 600 square miles while blizzards are limited to much smaller areas. To compare and contrast hurricanes and blizzards, the main points of interest are how these natural phenomena are formed, and the destruction associated with them.
Ryan Rosier Mrs. Ball English 9 February 27, 2014 Hurricane Katrina As Hurricane Katrina struck land in New Orleans people who didn’t leave the city were staring down the barrel of a loaded gun. Only Katrina’s gun was loaded with 140 mph gale force winds and crushing flood waters. The effects of the hurricane’s wrath were devastating enough to cause 75 billion dollars in damage. (Hurricane Katrina) Raging through while demolishing buildings, leveling entire suburbs, and taking thousands of lives was what this storm was hell bent on accomplishing. For those who didn’t leave the city, whether they couldn’t afford the costs, seeked the thrill of the storm, or just simply didn’t wanna leave on the opened interstates, (Beller) the storm
While hurricanes can produce extremely powerful winds and rain, they are also able to produce high waves, damaging storms, and tornadoes. Hurricanes are

Previous to Andrew was Hurricane Betsy, which was only a level three. The ranges vary between one and five. One is the lowest possible type of hurricane, a step above a tropical storm. The highest is a level five which has gusts of wind larger than one hundred and fifty miles per hour. The devastation caused by Andrew was over a very narrow region
