Disasters happens, in this situations information is everything.

Is there any information system that works worldwide and would:

  • Notify the possible victims that the something is coming (in cases it is possible to figure out before)
  • Provide useful information during/after the catastrophe:
    • water sources in case of fire/lack of water
    • missing person reports
    • damaged area information
    • where to get help, what help is on the way
    • etc...
  • Are you looking for something like en.wikipedia.org/wiki/Common_Alerting_Protocol

  • Google's people finder might be something you'd be interested in.

As far as I know there is no system in use that would alert people before the disaster.

To all the other questions, quite a lot of countries have adopted Sahana Eden, that does all the tasks related to the Management of the Disaster, including all the information you have putted there and a lot more...

It has been deployed in large disaster scenarios and it is "as good as it gets", also it complies with UN Standards!

    Could you please add more information about the Sahana Eden project as well as a link? Sounds interesting! Commented May 9, 2013 at 9:02

    I'm not sure it is correct to say that you can't alert before a disaster. In Japan they have warning systems for earthquakes. Since an these take a matter of seconds to propagate across the country, they are able to make a message appear immediately on everyone's mobile phones allowing them to get under a table or out of a building. In addition, their bullet trains to stop dead.

The two most promising open source solutions for disaster management seem to be Sahana Eden and Ushahidi. To quote from their respective websites:

Sahana Eden:

Sahana Eden is an Open Source Humanitarian Platform which can be used to provide solutions for Disaster Management, Development, and Environmental Management sectors.

Ushahidi Platform:

You can use the Ushahidi Platform for information collection, visualization and interactive mapping.

According to this overview article on Sahana Eden, the two tools can even be integrated:

Sahana Eden is also able to integrate with other solutions and can provide a management/ticketing interface around crowd-sourced data - such as that collected in the Ushahidi incident mapping application.


The Global Disaster Alert and Coordination System should address the alert part.

GDACS is a cooperation framework between the United Nations, the European Commission and disaster managers worldwide to improve alerts, information exchange and coordination in the first phase after major sudden-onset disasters.

As for the coordination of relief etc, I don't think there's a worldwide system for that. The closest I can think of would be the UN OCHA humanitarian response sites.
