  1. CAMP ATTERBURY JMTC Tornado Safety Slideshow This is the oldest known photo of a tornado. It was taken on August 28, 1884 near Howard, South Dakota. The name of the photographer is not known. Brought to you by the Camp Atterbury Directorate of Emergency Services

  2. Hey Elsie, What is that? I bought you a stairway to heaven…

  3. A tornado is defined as a violently rotating column of air extending from a thunderstorm to the ground, the result of a clash between two air masses of widely different temperature. In an average year, about 1,000 tornadoes are reported across the United States, resulting in 80 deaths and over 1,500 injuries. The most violent tornadoes are capable of tremendous destruction with wind speeds of 250 mph or more. Damage paths can be in excess of one mile wide and 50 miles long.

  4. Indiana has a yearly average of 23 reported tornadoes. Indiana tornadoes have occurred in every month of the year. On June 2, 1990, 37 tornadoes ripped through Indiana, the most on any one day in state history. Camp Atterbury lies in three south central counties: Johnson, Bartholomew and Brown, where there have been no reported deaths attributed to tornadoes since 1950. This tornado was obviously in Kansas.

  5. Environmental Clues Look out for: Dark, often greenish sky Wall cloud (seen here) Large hail Loud roar; similar to a freight train

  6. This 3 ½ minute video, recorded in 1997 on the Kansas Turnpike, illustrates the great changes in intensity that take place during the span of time that a tornado is on the ground. It is also a terrific example of the sound one would here when near a tornado because the photographer actually keeps his mouth shut. (Watch at the end for the wonderfully helpful police officer scolding the woman and children under the bridge) click image for video

  7. As was seen in the previous video, flying debris is also a concern.

  8. FUJITA SCALE Level Wind Speed Possible Damage F0 40 - 72 mph Light damage: Tears branches from trees; rips shallow-rooted trees from the ground; can damage sign-posts, traffic signals and chimneys F1 73 - 112 mph Moderate damage: Roofing materials and vinyl siding can be displaced; mobile homes are highly vulnerable and can easily be knocked from the foundation or toppled; motorists can be sent careening off road and possibly flipped over F2 113 - 157 mph Considerable damage: Well established trees are easily uprooted; mobile homes are dessimated; entire roofs can be ripped off houses; train cars and trucking hauls are knocked over; small objects become dangerous missiles F3 158 - 206 mph Severe damage: Forests are destroyed as a majority of trees are ripped from the ground; entire trains are derailed and knocked over; walls and roofs are torn from houses F4 207 - 260 mph Devastating damage: Houses and other small structures can be razed entirely; automobiles are propelled through the air. F5 261 - 318 mph Incredible damage: Cars become projectiles as they are hurled through the air; entire houses are completely destroyed after being ripped from the foundation and sent tumbling into the distance; steel-reinforced concrete structures can be seriously damaged.

  9. A Tornado Watch means that conditions are favorable for tornadic activity. A Tornado Warning means that one has been spotted or computers have indicated rotation in the storm.

  10. Do: *Secure potential flying debris *Be sure that others are aware of developments *Seek shelter immediately in a windowless interior room *If no shelter is available, cover your head with your hands in a ditch or ravine *If you must make a phone call, use a cell phone, landlines are a lightning hazard Note: Tornadoes generally travel in a southwest to northeast direction Do Not: *Stay in your car and try to outrun the tornado *Get near any window *Ignore tornado warnings and continue to watch the wrestling match in your mobile home
