The most difficult period of a disaster is the immediate aftermath. This period calls for prompt
action within an exceptionally short period of time. In the aftermath of any disaster, a significant
number of individuals will be injured and/or displaced.Many of them may still be living with the
trauma they have encountered, including loss of loved ones. Affected individuals may also be
without food or other essential items.They might be waiting in temporary shelters, with no idea
what to do next. Some might need immediate medical attention, while the disaster aftermath
environment also creates ideal breeding grounds for possible epidemics.
Charged with leading the response, authorities may find themselves with limited resources and
without any comprehensive plans to use them or to find more. They often need the help of a
third party, which can include donors, both institutions and individuals. These institutions may
have assistance to offer, but know no means in which they can provide it as they may not have
any link with those who are working in the field.
The following case studies illustrate how ICT can be used effectively to address such problems
in the immediate post-disaster period.
Case Study 1: Sahana Disaster Management System in the Aftermath of the Indian Ocean Tsunami in 2004 and Pakistani Earthquake in 2005
Sahana, a free and open source software (FOSS)-based system developed by Lanka Software
Foundation, is a suite of web-based applications that provides solutions to the problems arising
in a post-disaster situation. The following examples show how Sahana assisted disaster victims
during the Indian Ocean tsunami in 2004 and the Pakistani earthquake the following year.

Example 1: Tracing Missing Persons
After a disaster, there are often a large number of individuals missing. It is common to find
families scattered and children separated from their parents. Outside relatives and friends,
especially those living overseas, naturally want to know the latest information about the
condition of their loved ones. The psychological strain on children can be severe and it is
essential that they be reunited with their families as soon as possible.
One objective of Sahana is to assist victims in connecting with their families and friends as soon
as possible. Sahana’s Missing Person Registry is an electronic version of a bulletin board of
missing and found people. It can capture information not only on the people missing, but also
about those who seek details about the missing, thus increasing their chance of reuniting. Even
if the victims or families do not have access to this information themselves, it is quite easy for
any authorized NGO or civil society group to connect to the central portal and provide that
service in the areas they are working.
Example 2: Coordinating Donor Groups
In the immediate aftermath of the 2004 tsunami in Sri Lanka, there was a massive outpouring of
support from international NGOs, local NGOs and community groups. There were at least 300
NGOs working on the same goals, though they used different approaches. In an environment
where resources are in short supply, it is essential that response efforts should not be
duplicated. Otherwise, such duplication can result in issues such as congested supply routes,
competition between organizations, double vaccinations and saturation of support provided to
some areas while other affected areas are neglected. Consequently, goodwill can be lost.
This coordination task is too much for an authorized emergency controller to handle manually.
An ICT solution can thus be the ideal solution. For instance, an electronic organization registry
can help immensely. It can effectively track who is doing what, where, when and, more
importantly, whether there are areas in which services are not adequate. This awareness can
enable volunteers and organizations to distribute themselves evenly across affected regions.
Sahana has developed such an organization registry. It keeps track of all the relief organizations
and civil society groups working in the disaster region. It captures information on both the
places where they are active and the range of services they are providing in each area to ensure
that there is no overlap.
Example 3: Recording the Locations of Temporary Camps and Shelters
In a disaster situation, there are usually no pre-planned locations for camps and shelters.
A temporary shelter or camp can be anywhere and can range in size from a large
government-maintained camp to an individual house. Due to these differences, it is necessary
to record the locations and populations of all camps. This is paramount to distributing aid
effectively and ensuring that no affected areas are inadvertently ignored. A sub-application of
the Sahana system keeps track of the location of all the camps in the region. It also records basic
data on the facilities they might have and the number of people in them. If necessary it can
provide a GIS view to plot the location of the camps in the affected area (De Silva, undated).
Case Study : Use of Internet in the Aftermath of the 1999 Earthquake in Turkey
On 17 August 1999, a major earthquake caught people off guard in Izmit, Turkey, resulting in
15,000 deaths. A second earthquake occurred on 12 November of the same year in Duzce,
claiming 1,000 lives. In addition to these casualties, almost twice as many people were displaced
as a result of both events. A total of 120,000 houses were damaged beyond repair while 50,000
houses were partially damaged.
During the Izmit earthquake, telecommunications infrastructure was so extensively damaged
that it was impossible to access emergency services. The use of public phones was almost
impossible, while mobile phone networks were operating with reduced bandwidth. In addition,
many of the microwave repeaters mounted on apartment buildings had been damaged during
the quake. In this situation, Internet was the only possible medium that could connect the
affected areas to the outside world. Several Internet applications were used in the post-disaster
response, mainly in two key areas: coordination of aid disbursement and finding information
about missing people.
Due to system disruption, donors often found themselves acting as the distributors of aid as
well, thus, the Internet proved a valuable resource. NGOs played a central role in the provision of
discussion lists for the coordination of donations so that donors could find the most in need,
identify what they were in need of, and in some cases, determine how to get there. Internet was
also used to provide information regarding the whereabouts of missing family members. For
example, many organizations formed ‘message lines’, which acted as a database of people
found, their condition or the degree of damage to the region in which relatives lived
(Zincir-Heywood & Heywood, 2000).
The importance of information security and privacy can never be underestimated in ICT-based
humanitarian systems. In these cases, data privacy is not just a matter of encryption, it can also
be a matter of life and death. If data falls into the wrong hands, it can result in rape and sexual
harassment, child and female trafficking, child soldier recruits, prostitution and even ethnic
cleansing. This is especially the case when a disaster occurs in an ethno-politically volatile
region, where the technology and frameworks conceptualized and implemented need to be
deeply cognizant of ground realities and tensions between ethnic groups, factions and
non-state actors.
Case Study 3: UNOSAT’s Role in Disaster Response During the 2004 Indian Ocean Tsunami6
The United Nations Institute for Training and Research Operational Satellite Applications
Programme (UNOSAT) provides the international community and developing countries with
enhanced access to satellite imagery and GIS services. These tools are used mainly in
humanitarian relief, disaster prevention and post-crisis reconstruction. UNOSAT also acquires
satellite images from all commercial providers.
UNOSAT provides services on:
Image processing;
Map production;
Methodological guidance;
Technical assistance; and
Training.
The UNOSAT core team consists of UN fieldworkers as well as satellite imagery experts,
geographers, database programmers and Internet communication specialists. This unique
combination gives UNOSAT the ability to understand the needs of the users and to provide
them with suitable, tailored solutions.
UNOSAT has been active during many recent disasters.When the Indian Ocean tsunami struck
on 26 December 2004, UNOSAT provided an immediate overview of the situation prior to
triggering the International Charter Space and Major Disasters the day after. UNOSAT
immediately created regional maps of potential impact and more focused maps of the areas
reported to be heavily affected in the first days after the disaster. The first UNOSAT map was
on-line and distributed to field users on 29 December 2004. Satellite image analyses and map production provided UN colleagues and the international
humanitarian community with regional and local damage assessment maps using a wide range
of satellite sensors.The Imagery Bank was on-line as of 14 January 2005 with a large amount of
free satellite data obtained through the Charter and the US Government.Currently,over 670 raw
satellite images and over 200,000 tsunami maps are available on its website at
