2004 Tsunami (indian ocean earthquake) and how infromation was sent

When the Tsunami was detected E-mails were sent to the more developed parts of Asia whereas the less developed areas were left out leading to them getting less indication of the Tsunami.
With the E-mails being sent out information was shared quickly allowing more developed areas of Asia to try and protect themselves.
The interaction between others and organizations was through text messages as the phone lines were down and all the computers were not working allowing text messages to be sent quickly between people.
Online Groups were set up to help raise money for the Tsunami and it brought the community together and allowed larger groups of people help a good cause.
Modern communication services are used more than older ones because more people are able to access then at once allowing large numbers of people to communicate at the same time.
The services used were put to there purpose perfectly as relatives of people in the Tsunami were able to contact them quickly allow relatives to be relived.
