Disasters confirmed by OCHA Virtual OSOCC
Events in this list are currently actively discussed in the UN OCHA's Virtual On Site Operations Coordination Centre.
The main purpose of the Virtual OSOCC is to facilitate decision-making for
international response to major disasters though real-time information exchange
by all actors of the international disaster response community

Updated Flood Waters in Charsadda and Nowshera Districts, Pakistan
UNOSAT
9 Aug 2010 2:37:35 PM This map presents an analysis of standing flood waters over the affected Charsadda and Nowshera Districts, Khyber-Pakhtunkha Province, Pakistan, based on post-disaster RADARSAT-2 data from 5 August and MODIS on 31 July 2010. Pre-flood water data was obtained from RADARSAT-1 satellite data (1 Dec. 1999). There are strong indications that flood water levels have significantly receded along the upstream sections of the Swat and Kabul Rivers north of Charsadda before the confluence, and over a 15km section of the Kabul River downstream of Charsadda. The bulk of standing flood waters within 10km upstream of Nowshera city appear to be receding at a much slower rate leaving the total area of standing flood waters on 5 August similar to that of 31 July 2010. Water levels a kilometre after Nowshera city along the Kabul River towards the Ghazi Brotha dam appear also to have receeded to a significant degree. Please note: there are several associated levels of uncertainly with this analysis due to the limitations of comparing radar and optical satellite data with different spatial resolutions. It is likely that the extent of the flood waters detected on 5 August has been underestimated along some sections of the Kabul River within the map extent. The exact limit of the MODIS flood water detection on 31 July 2010 is also uncertain because of the relatively low spatial resolution of the sensors used. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

Damage Overview of Flood-Affected Towns In Nowshera District, Khyber Pakhtunkhwa, Pakistan
UNOSAT
5 Aug 2010 9:10:52 PM Analysis Description: This map presents the preliminary findings of a damage assessment over sixteen flood-affected towns and cities along the Kabul and Kalpani Rivers including the main city of Nowshera, Nowshera District, Khyber Pakhtunkhwa, Pakistan. This analysis is based on post-disaster Worldview-1 satellite imagery collected on 2 August 2010. All road and bridge damages related to the flooding have been individually identified and marked within the map; flood-affected towns and villages have been classified by the relative degree of flooding impact and the approximate number and extent of building damages as visually identified in the satellite imagery. Not all flood related damages have been identified because of limits in spatial resolution of the imagery used and due to heavy cloud cover over the assessed area; damages identified are likely to be underestimated. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT. Map scale for A3: 1:44,000; Projection : UTM Zone 43N; Datum : WGS-84. |
