Emergency Alert System Tornado Warning: Its Role and Mechanism

Emergency alert system tornado warning is needed to give attention to people to avoid dangerous areas where tornadoes will occur. Have you ever seen a tornado? It is categorized as a natural disaster with complex damage.

A tornado is a column of air like a spiral that rotates rapidly until touches the ground. This natural phenomenon often occurs during severe thunderstorms, especially when hot and humid air meets cold and dry air. This meeting causes instability in the atmosphere, precisely in the area of ​​cumulonimbus cloud formation to the ground surface.

Role of Emergency Alert System Tornado Warning

Emergency alert plays an important role in public safety in disaster-prone areas. The possible impacts can also be minimized. This warning is issued if there are signs of an impending disaster. It also applies in tornado cases.

If there is an emergency alert system tornado warning, it means to must be alert and immediately prepare to avoid dangerous areas as informed. The scope of the dangerous area is quite wide, including several districts or states. Generally, the span time from the emergency alert to the appearance of a tornado is about 30-60 minutes. 

By providing this emergency alert, hoped that more people will be protected and have more time to move to the safer zone. An effective emergency alert system will increase the success of disaster management. The government together with other agencies need to ensure the availability of this system.

Mechanism of Emergency Alert System

An emergency alert is not issued haphazardly. In the case of tornadoes, the warning system applies when signs of a tornado appear. For more details, see the mechanism for issuing emergency alerts for tornado disasters below.

1. Monitoring and Detect the Emergency Situation

Same with the previous explanation, emergency alerts will only be given if there is a potential disaster. To find out whether or not there is such potential, monitoring is carried out by authorized institutions. To detect tornadoes, two types of observations can be used, such as visual and non-visual.

Visual observations are made by observing several signs. First, the shape of the cloud. If there is a funnel cloud and rotates, it causes a tornado. If there is no funnel cloud but a cloud of debris approaching the ground, that's also a sign.

The second sign is a dark sky. The sky suddenly becomes dark, especially in cumulonimbus clouds that have a large volume. Third, dust vortex. If it appears on the ground and then merges with the base of the cloud, it potentially causes a tornado.

Non-visual observations are marked by a rumbling sound like a train or a crowd of running animals, temperature changes from hot air suddenly accompanied by cold air, and the calm atmosphere suddenly occurs after a storm with the sky remaining dark.

2. Applying Early Emergency Alert System

If there is a potential for a tornado, an emergency alert is given. The purpose is to reduce the impacts caused by a tornado, which is included in the terrible disaster. The power of a tornado is huge. It can reach 177 km/hour and as far as 75 meters.

The implementation of this emergency alert system includes early warning and evacuation warning. Both are given sequentially. After being declared a potential tornado, an early warning is issued which informs the location of the disaster and how big the impact will be.

3. Applying Evacuation Warning System

Sometime after the early warning, an evacuation warning is given to encourage people from disaster-prone zones to move to safe zones. The relevant parties must have previously determined evacuation routes and temporary refugee camps until the situation is safe.

As the first party responsible for protecting the community, the government facilitates mitigation efforts carried out before, during, and after a disaster. In the case of a tornado disaster, one of the facilities needed is to provide an emergency alert system tornado warning.

That is a tornado emergency alert system that helps the surrounding community save themselves before a disaster occurs. This system is even more effective if equipped with an emergency message-sending machine via SMS (Short Message Service).

This system allows the information can be sent directly to community mobile phones, so it is distributed faster, in real-time, and evenly. This specific technology machine is available at smsbroadcaster.com which is supported with various important information.
