DAMAGE ASSESSMENT SUMMARY:
This is a quantitative damage summary for the city of Osh based on a detailed analysis of crisis satellite imagery acquired on the morning of 18 June 2010. A total of 1,877 affected buildings were identified within the city of Osh. Of this total, 1,805 buildings were totally destroyed and 72 were severely damaged. A further 73 SOS distress signs and 32 roadblocks were also identified as likely indications of distressed ethnic-Uzbek neighborhoods. As illustrated in the overview map on page 3, a density analysis of the affected building sites indicated there are seven major clusters of destruction located along an approximate east-west axis through the center of the city. Within these spatial clusters there is a pronounced degree of damage type homogeneity of near total building destruction, with sharply defined boundaries between affected and unaffected neighborhoods.
A preliminary assessment of building damage signatures indicates that arson was the probable cause because of the prevalence of destroyed rooftops with visibly intact load-bearing walls, a common signature of fire-related damages; a finding supported by the satellite detection of six active fire zones within the city at 6:25 UTC (12:25 local time) on 12 and 13 June 2010. 52% of affected buildings identified in the satellite imagery of 18 June also fall within the six active fire zones, suggesting that a majority of the building destruction likely occurred as a result of the detected afternoon fires on 12 and 13 June 2010.
A significant majority of affected buildings are directly accessible from main primary or secondary roads suggesting that the suspected arson attacks were perpetrated by individuals or groups who restricted their movement to these main transport routes. Almost all affected buildings appear to have been residential or situated within residential neighborhoods, however there are a few cases of destroyed or severely damaged industrial warehouses or commercial / government facilities. No damages have been observed to the transportation network (e.g. roads, bridges) or other key infrastructure sites within the city.
There is compelling evidence to suggest that there are several ethnic-Uzbek neighborhoods within the city of Osh that are potentially still heavily populated and relatively undamaged by the reported arson attacks. These distressed neighborhoods have been identified by the presence of multiple road blocks at main road and bridge entry points, as well as the presence of multiple "SOS" signs painted on interior roads within clearly defined residential areas. In most of these neighborhoods, a large majority of buildings appear to be undamaged and thus could still provide shelter to thousands of local residents. A small number of damaged buildings identified outside of the main damage clusters may be unrelated to the recent conflict, possibly due to recent construction / demolition or accidental house fire.
