    This map illustrates satellite-detected damaged structures in San Julian Area, Eastern Samar Province, Philippines. Using an image acquired by the WorldView-2 satellite on 12 December 2014 and compared with WorldView-1 image collected on 12 July 2014, UNOSAT identified a total of 279 affected structures in the area. Specifically, 66 structures were categorized as destroyed, 148 as severely damaged and 65 as moderately damaged. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

    This map illustrates areas affected by Pico de Fogo volcano as seen in a Landsat-8 image acquired 24 November 2014. The 23 November 2014 eruption, the first since 1995, occurred through a subsidiary vent located in the western flank of the Pico de Fogo mountain. The main cone seems to be not involved in the eruption as of the 24 November 2014 image acquisition. About 5,700 meters of roadways in the caldera area seem to be affected by the lava flow and are potentially out of use including the road from the Caldera to Sao Felipe city. The inset of this map illustrates the lava flow and smoke as seen with false colours as captured by Landsat-8 image. Note that the lava flow is likely underestimated because of smoke. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR /UNOSAT.

    This map illustrates satellite-detected areas of IDPs in Bor UNMISS Base and Protection of Civilian (PoC) areas, in Jonglei state, as seen by the WorldView-3 satellite on 8 October 2015. The IDP structures were moved from the old PoC area in the northeast of the base to the new PoC area found in the south, and currently all the IDP shelters are now entirely in the southern extension of the UNMISS base. There are currently 1,077 structures in the IDP settlement with 101 consisting of infrastructure buildings and 976 of shelter structures. A large part of the camp still remains unoccupied and this can be seen as the Contingency area. This is a preliminary analysis and has not yet been validated in the field.

    This map illustrates satellite-detected flood waters in the centre of Sagaing State in the areas of Kawlin, Kanbalu,Taze and Kyunhla Townships of Myanmar as imaged by the Radarsat-2 satellite on 30 July 2015 and compared with Sentinel-1 satellite data on 18 July 2015 and Landsat-8 satellite acquired 29 April 2015. There is a notable increase in the expansion of reservoir compared to the previous weeks. Note also, many of inundated areas are swamps which are regularly flooded in the rainy season and as the river expands. This is a preliminary analysis and has not yet been validated in the field.

    This map illustrates satellite-detected damaged structures in Dolores City, East Samar Province, Philippines. Using an image acquired by the WorldView-2 satellite on 12 December 2014 and compared with an image collected on 19 June 2014, UNOSAT identified 597 affected structures in the area. Specifically, 193 structures were categorized as destroyed, 225 as severely damaged and 179 as moderately damaged. Note that due to significant cloud cover present on the post-event image, the north and northwestern parts of the city could not be analysed. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

    This map illustrates satellite-detected areas of destruction in the town of Rubkona as seen by the Ikonos satellite on 13 January 2014. UNOSAT analyzed all structures in the town to verify reports of damage and determined that the majority of the town has been destroyed, primarily by fire. A total of 3,996 burned or otherwise destroyed structures were identified throughout the town center as well as in outlying areas surrounding Rubkona. In addition, indications of looting consisting of debris piles were evident in multiple locations. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

    This map illustrates satellite-detected areas of destruction in the town of Bor as seen by the WorldView-1 satellite on 19 January 2014. UNOSAT identified a total of 1,962 destroyed residential and related structures and a total of 93 warehouse or commercial structures were identified throughout the area analyzed, with the heaviest damage in the downtown area of government buildings. The destroyed structures comprise an estimated 8.4% of the total number of pre-conflict structures in Bor. This analysis covers only the period from 25 December 2013 to 19 January 2014 and damage occurring before that time may not have been identified. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.

    This map illustrates locations of destroyed structures in the area of Paoua, Central African Republic. Using a satellite image acquired 18 June 2014 and compared to an image from 12 January 2012, UNOSAT reviewed the town of Paoua and surrounding areas to locate obvious signs of destroyed structures (see inset for example). An estimated total of 323 destroyed structures were located in the area as well as 25 possible damage structures, both in Paoua and in outlying towns and villages. The destroyed structures comprise an estimated 2.2% of the total number of pre-conflict structures in Paoua.Most destruction detected in the 18 June image was most likely a result of burning given the blackened structural remains visible in the imagery. This is a preliminary analysis and has not yet been validated in the field.

    This map illustrates locations of destroyed structures in the area of Marcounda Sub-Prefecture in the Central African Republic. Using satellite images acquired 21 June, 23 June & 7 July 2014, UNOSAT reviewed almost 4,500 square kilometers of Marcounda to locate signs of destroyed structures. An estimated 3,840 damaged structures are visible across 50 distinct locations in the sub-prefecture. Destruction in many cases was likely due to arson based on appearance of structural remains. In addition, it appears violence and destruction continued between 21 June and 7 July, and heavy rains apparently caused significant damage to structures as well. Overall, UNOSAT estimates that approximately 40% of structures in Marcounda Sub-Prefecture have been completely destroyed and many others are likely damaged to some degree. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR / UNOSAT.
