Communication and the Internet part 2

Communication is very important in emergencies such as natural disasters. By communicating millions of people's lives can be saved. Not only that, medical supplies and other necessities can be sent from other countries to help the horrible situation.

Many different techniques of communication were used during Hurricane Katrina and Asian Tsunami. Ham operators were one of the ways that helped to communicate in hurricane Katrina using voice, computers, televisions and Morse codes. Some hams bounce their signals off the upper regions of the atmosphere, so they can talk with hams on the other side of the world; others use satellites. Many use short-range, handheld radios that fit in their pockets. Cellphones were a vital aid in communicating to get help. Families were able to text or call friends or other relatives in different parts of the world to get help. If they were to try to call the police the system would probably be overloaded. There are still many other sorts of communication used in now a day natural disaster.

The essential information needs to be communicated during a disaster or emergency are:

- The type of emergency, the affected areas and populations and the emergency likely progress.

- It's impact on health.

-The immediate impact on health services

- The extent of damage to other areas similar to health operations

During a natural disaster you can make precautions before it happens. For example, if there is a hurricane or tornado, you can get underground in a shelter to avoid the disaster. The tornado can't blow away an underground shelter. Even if you do this, you must take supplies like water and foods for this as you do not want to be stuck underground without any food or water and starve.
