Tornado warnings are for an area, usually by county or parish. If a home resides within a county or parish in which a tornado warning has been issued, than the home is at risk and the head of household should see fit to warn the inhabitants of that home. Heading to the lowest place in the house is best, and at that one should station themselves under a header, sturdy beam, or under a strong table if necessary (in case of falling debris, or collapse)

One system is based on spiking electrical signals in the ground before a quake which are monitored by several private companies and radio amateurs in the California area now. Another system is the heating of the fault zone before a quake which sometimes causes ground water vapor formation in the form of a cloud that stretches out like a smoke trail from the hot point on a fault and can sometimes be seen on a satellite before a quake (several amateurs on websites monitor these from weather satellite photos).
None of those work EVERY time but depending on circumstances can give warnings for SOME quakes.
For example the amateur radio group correctly saw electric warnings of quakes in LA 2 days in advance several times. some middleeastern quakes have been proceeded by earthquake clouds which were noticable on weather satellites.
In addition most large quakes are more likely to happen when the moon is high or low in its position compared to the earth's equator. (That's different than just being high or low in the sky or in a certain phase.) That just increases the probability however and is not a sure sign.
The Japanaese government monitor earthquakes and send an instant cell phone alarm to anyone in a large area that will feel that quake so they have some small seconds to take cover before they feel the shaking waves. It owrks best if the quake is very large and far away so the alarm reaches you longer before the waves have a chance to travel to you through the earth.
One easy system similar to the Japanese phone system relies on another way of getting a few seconds warning. It is the most practical low cost warning system I have found called the "Earthquake Alarm" and is about the size of a smoke alarm which hangs on your wall and can feel the much more subtle P wave which travel faster than the more shaking S wave and thus - like seeing lighting several seconds before distant thunder- can give you several seconds before a large quake may shake you.
I personally have had the earthquake alarm give me 40 seconds warning before the shaking from a the Mexican border quakes hit my home in Los Angeles so I KNOW this works if the quake is large and if it starts several miles away from you. It should work well for any earthquake on the San Andreas if you live in Los Angeles.
I got mine off electricquakes dot com.
It makes a huge difference to have 30 seconds warning before you feel the shaking so you have time to get out of bed and stand outside or somewhere safer than bed.

∙ 10y agoYes. The United States in particular has an advanced warning system that makes use of a combination of conventional weather forecasts, Doppler Radar, and trained weather spotters to warn people about the possible threat of tornadoes.
Wiki User
∙ 11y agoYes. The precursor to a tornado can be detected by doppler radar. This tool cannot predict with certainty that a tornado will occur, but it can show if a storm is the potential to produce a tornado.
Wiki User
∙ 10y agoTo some degree. The United States in particular has a state-of-the-art advance warning system. Dopper Radar can detect tornadoes and storms capable of producing them. This, combined with eyewitness reports, is used to send out warnings, which are broadcast through TV, radio, the internet, and even smartphone apps. Some communities in tornado prone areas sound sirens in the event of a tornado warning.
Wiki User
∙ 8y agoA tornado warning is an advisory that is issued when a tornado has either been spotted or detected or that a thunderstorm in the area is likely to produce a tornado soon.
Wiki User
∙ 13y agoMany cities and towns in tornado prone areas have sirens, much like air raid sirens, that are sounded during a tornado warning.
Wiki User
∙ 13y agoThe NOAA can issue warnings over the radio if a tornado has been detected by a Doppler radar or if someone has phoned the NOAA saying they've spotted a tornado.
Wiki User
∙ 11y agoYes. Doppler radar and dual-polarized radar can be used to detect a tornado.

How does prediction help the people in dangers way for tornadoes?
Predicting a tornado allows us to warn people in the path, allowing them to get to a safe place before it hits. In the days before we had tornado warnings many people were killed or injured because tornadoes caught them unprepared.
Can you control where a tornado hits?
No. There is absolutely no way for people to control anything about a tornado.
Is there going to be a tornado in Houston?
There probably will be eventually, as Houston is in a fairly tornado-prone area and has been hit before. However, there is no way of knowing when such an event will occur.
Is there any way to prevent a tornado?
No. There is nothing that can stop a tornado that we, as people, have any means of controlling.
Where do tornadoes occur most frequently?
Tornadoes occur the most in Tornado Alley, a region in the United states that includes Texas, Kansas, Oklahoma, Nebraska, Missouri, South Dakota and Iowa. While tornadoes can occur elsewhere, nowhere else in the world do they occur more frequently.

What is a tornado that doesn't occur on land?
A tornado that doesn't reach all the way down is a funnel cloud. A tornado on water is a waterspout.
Are people expeting a tornado today?
There is a possibility of tornadoes today (May 12, 2011) but there is no certainty, and there is not way of telling exactly where or what time they will occur.
What are the wave height of a tornado?
There is none. Tornadoes are not waves, they are violent whirlwinds and they generally occur on land. When they do occur they do not produce much in the way of waves, as the winds of a tornado only cover a small area.
Can you control where a tornado hits?
No. There is absolutely no way for people to control anything about a tornado.
How was the Edmonton tornado first recgonised?
their was a man that was driving out side of edmonton. he saw the funnel cloud start to form and heard weather warnings on the radio so he phoned in to warn them that their was a tornado on its way to edmonton.
Is there going to be a tornado in Houston?
There probably will be eventually, as Houston is in a fairly tornado-prone area and has been hit before. However, there is no way of knowing when such an event will occur.
Is there any way to prevent a tornado?
No. There is nothing that can stop a tornado that we, as people, have any means of controlling.
When is there going to be another tornado in Kentucky?
Yes. It is inevitable that there will be tornadoes in Kentucky in the future. But there is no way of knowing where or when they will occur.
Will there be a tornado?
There will certainly be tornadoes in the future, hundreds of them happen every year. But there is no way of knowing exactly where or when they will occur.
Why is it important to issue tornado warnings as early as possible?
I used to live in Tornado Alley... a tornado watch means that the weather conditions mean it is very likely that a tornado will form in an area. A tornado warning means a tornado has touched down nearby.
Will there ever be another tornado that kills more than 100 people?
There is no way of knowing for certain. However, recent events indicate that such an event may occur eventually. After 1953 we went several decades without a tornado killing more than 100, and some came to believe that warnings had become advanced enough to make such deadly tornadoes a thing of the past. However, on May 22, 2011 an EF5 tornado struck Joplin, Missouri, killing 158 people. Elsewhere in the world, where tornado warnings are nonexistent, extremely deadly tornado do occur. On April 26, 1989 a tornado tore through the cities of Daulatpur and Saturia, killing an estimated 1,300 people. This tornado, which is usually overshadowed by tornadoes in the U.S., stands as the deadliest tornado ever recorded.
