Societies have been battling the impact of disasters on their lives from the very beginning of their existence. A disaster is a challenge in more than one aspect, it has a devastating effect on a society and thus forcing change on the way a society lives, this change is the real measure of a disaster’s impact regardless of numbers and quantifiers. The impact differs from one society to another, depending on the degree of disaster’s preparedness the society possesses. Therefore it is very important to start mitigating disasters before they occur and one important part of this process is insuring a high level of survivability for the infrastructure. This study addresses the effect of accidental disasters on computer networks due to the importance of computer networks for everyday life and even more so during crisis times. The paper uses disaster’s information from the Tohoku 2011 disaster and network traffic data from MAWI archive during the time of the disaster to validate the Accidental Disaster Network Impact Model (ADNIM). The model is a tool that estimates the change in network traffic during the event of a topological network failure that is triggered by an accidental disaster. The results from scenarios calculation show that the model is able to calculate scenarios that are closely similar to the real disaster time events.
