The deadliest tornado was the 1969 Bangladesh tornado that left 1300 dead. Tsunamis form as the result of a displacement on the sea floor typically caused by fault movement that also generates an earthquake. The Sumatra event occurred as the Indian Plate subducted under the Burma Plate.
How tornado sirens work?
The tornado sirens are activated with a signal from the NWS that indicates a tornado has been spotted or is strongly indicated on a Doppler radar and/or strong, damaging winds of 70 mph or greater are present. The alert goes off in the specific cities or towns that will be affected, not throughout the entire county.
The next thing we wondered was: what to do if you hear a tornado siren?
Tornado Warning means a tornado has been sighted or indicated by weather radar. Take shelter immediately. It’s important to know how to stay safe if a tornado is in the area. Learn what to do if a tornado strikes while you are at home, in a mobile home or at school. Watch the videos.
Three siren tones are used in the country: Warning: a 2 minute long steady tone. Used to warn of the impending danger of a fire, environmental or other disaster, or high water level. Immediate danger: a 1-minute wailing tone. Used to warn of the danger of a major fire, flood, radiological or chemical danger, or air raid. All clear: a 30-second steady tone.
Tornado sirens tend to go off after a Tornado Warning has been issued. Tornado Warnings are when either rotating cloud bars have been spotted or have been indicated on radar. You will generally hear your cellphone go off first, this is because it automatically activates an alarm on your phone.
Original sirens were put in place to warn of nuclear attack. Most systems are now more than 50 years old. Old system often could not be heard indoors.
What do tornadoes sound like?
Sound Of A Tornado A loud continuous roar, rumble, waterfall sound, or sounds similar to a train or jet (which does not quickly fade out like thunder). Tornadoes are LOUD. Some describe the sound as a simultaneous lower-pitched roar (train rumble) and a higher frequency “whine” (like a low flying jet).

I discovered rumbles, Roars, and Whirs While the most common tornado sound is a continuous rumble or roar, a tornado can also make other sounds. In addition to a constant rumble or low roar, tornadoes can also sound like: A waterfall or whooshing of air. A nearby jet engine.
What did tornadoes sound like before trains were invented?
Answer: The freight train is the all-purpose simile. Old accounts likened the noise to “10 million bees” or “1,000 cannons.” Perhaps listeners on the Great Plains were reminded of buffalo stampedes.
Our best answer was usually, a tornado picks up and contains a lot of debris In a swirling torment of wind. Items and debris such as two by fours and glass shards and bricks and such. It would be as if you were dropped into a blender in the funnel. Or people are buried under tons of wreckage.
What are tornadoes and what causes them?
How long does a tornado last? Besides the United States, what other locations get a lot of tornadoes? Can hurricanes cause tornadoes?
How can we stop a tornado?
That would include: Installing a storm shelter in your backyard. Hiding in your basement or an interior room on the lowest level of a building. Lying flat in a ditch far away from large bodies of water like lakes (tornadic thunderstorms tend to be prolific producers of rainfall, posing a serious flooding risk).
