This is a quantitative damage summary for the city of Jalal-Abad based on a detailed analysis of crisis satellite imagery acquired on the morning of 21 June 2010. A total of 330 affected buildings were identified within the city of Jalal-Abad. Of this total, 291 buildings were totally destroyed and 39 were severely damaged. An additional 28 potentially damaged buildings were identified outside the main damage clusters but were likely the result of normal construction/demolition activities unrelated to the recent conflict. In contrast with the city of Osh, no SOS distress signs or roadblocks were identified within Jalal-Abad.
As illustrated in the overview map on page three, a density analysis of the affected building sites indicated there is a single major cluster of destruction located along two major intersecting roads within the Kugartskaya Dolina area of the city. This single major cluster contains 69.4% of all identified damages for Jalal-Abad. Two smaller clusters have also been identified in the Khazret-Ayub suburb. Within these three spatial clusters there is a high degree of damage type homogeneity of almost 90% building destruction. The boundaries between affected and unaffected neighborhoods in Jalal-Abad are significantly more diffuse and poorly defined than in Osh.
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. Although no active fires were detected in Jalal-Abad by satellite sensors (unlike in Osh and Bazar-Kurgan), this was likely the result of local cloud cover and/or the lack of sensor coverage when the fires were active. Because of this lack of corresponding sensor data, it is not possible to identify the probable date of when building damages occurred in Jalal-Abad.
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. The airport is likely fully operational and unaffected.
