until the tornado ends and then the people fall and die or get injured
Yes so long as you stay in it.
several minutes or hours
Storm spotters can help tell exactly were a tornado is and where it is going, so people in the path can be warned and get to safety.
It isn't. Although the eye of a tornado is relatively calm, to get to it you have to go through the core winds of the tornado. It would be impossible to stay in the eye for very long.
It is safest to stay underground if you hear/see a tornado.
The tornado is reported to have had a path length of 27 miles and an average forward speed of 35 mph, which works out to a duration of 46 minutes.
The police advised people to stay home during the tornado.
The duration of a tornado can vary greatly, from just a few seconds to several hours. The length of time a tornado stays on the ground depends on various factors such as the speed at which it is moving, the strength of the tornado, and the terrain it encounters.
A "double tornado" is scientifically known as a multiple vortex or multivortex tornado. In such tornadoes smaller vortices form within the main vortex of the tornado. These subvortices usually do not last long and individually do not impact the overall tornado very much. Rather than indicating a lack of organization in the tornado, a multivortex structure usually indicates a strong tornado.
The average tornado lasts for about 5 minutes.
No, as long as you stay in your innertube and listen to lifeguard directions to avoid any danger.
No. A "sand tornado" (which is a dust devil, not an actual tornado) will move in whatever direction the wind around it is blowing.
