“…Observation and analysis are strongly based on QuickBird satellite images which have the currently best available spatial resolution of 0.6 m. The recent emergence of commercial satellite sensors with very-high ground resolution, comparable to aerial photography, such as IKONOS, QuickBird or Orbview-3 (Birk et al, 2003) opens new perspectives for applications in the area of natural hazards. These may range from detailed mapping and assessment to disaster management and response (cf.…”

Abstract.A massive rock/ice avalanche of about 100×10 6 m 3 volume took place on the northern slope of the Kazbek massif, North Ossetia, Russian Caucasus, on 20 September 2002. The avalanche started as a slope failure, that almost completely entrained Kolka glacier, traveled down the Genaldon valley for 20 km, was stopped at the entrance of the Karmadon gorge, and was finally succeeded by a distal mudflow which continued for another 15 km. The event caused the death of ca. 140 people and massive destruction. Several aspects of the event are extraordinary, i.e. the large ice volume involved, the extreme initial acceleration, the high flow velocity, the long travel distance and particularly the erosion of a valley-type glacier, a process not known so far. The analysis of these aspects is essential for process understanding and worldwide glacial hazard assessments. This study is therefore concerned with the analysis of processes and the evaluation of the most likely interpretations. The analysis is based on QuickBird satellite images, field observations, and ice-, flow-and thermomechanical considerations. QuickBird is currently the best available satellite sensor in terms of ground resolution (0.6 m) and opens new perspectives for assessment of natural hazards. Evaluation of the potential of QuickBird images for assessment of high-mountain hazards shows the feasibility for detailed avalanche mapping and analysis of flow dynamics, far beyond the capabilities of conventional satellite remote sensing. It is shown that the avalanche was characterized by two different flows. The first one was comparable to a hyperconcentrated flow and was immediately followed by a flow with a much lower concentration of water involving masCorrespondence to: C.

The high mobility of the avalanche is likely related to fluidization effects at the base of the moving ice/debris mass with high pore pressures and a continuous supply of water due to frictional melting of ice. The paper concludes with implications of the Kolka/Karmadon event for worldwide glacial hazard assessments. It is emphasized that situations with large glacierized high-mountain walls with potentially unstable glaciers within impact distance need special attention and monitoring efforts.

“…These assets plus the multispectral, and hyperspectral assets offer important sources of quality and timely information that can serve the operational needs of the warfighter (Birk et al 2003). If these assets and their availabilities could be centrally scheduled, a tablet application with the ability to task any of these assets could be an extremely powerful tool in providing exceptional situational awareness.…”

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instruction, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information.

DISTRIBUTION / AVAILABILITY STATEMENTApproved for public release; distribution is unlimited. 12b. DISTRIBUTION CODE A 13. ABSTRACT (maximum 200 words)Tablet computing has the potential to reshape the scope of situational awareness. This is because application developers have derived uses for tablet devices that the original inventors did not intend and could not have imagined. One such application is to provide the ability for the warfighter to directly request aerial images from overhead assets, including unmanned aerial vehicles or satellites. Advancements in mobile technology and network connectivity have helped to overcome the challenges of information delivery, but there remains the challenge of real-time information. This thesis examines the concept of tablet-based information requests for real-time satellite tasking. As a proof-ofconcept, a tablet-based application is developed that enables the user to task a satellite system by interacting with a map. Requests are sent and processed by a server application and are then routed to the appropriate asset. Real-time response to the request is emulated using a detailed simulation model of a control moment gyroscope actuated spacecraft. Simulated images and spacecraft attitude errors are used to mimic the data collection process. This information is uploaded to the server for retrieval by the tablet application, thereby completing the request cycle and demonstrating the feasibility of remote satellite tasking using a tablet computer.

“…However, sensor costs have generally decreased, making high quality remotely sensed data more accessible (EPA, 2011). Additionally, it is very unlikely that managers of a sequestration project will commission unique satellite sensors for their specific project, but will more likely rely on an existing sensor operated by commercial or government entities, defraying development costs and risks to these outside vendors (Birk et al, 2003;Mumby et al, 1999). Select existing and proven remote sensing technologies applicable to their specific needs and budgets will allow site managers to keep costs and risks of using remote sensing technology at an acceptable level (Benson et al, 2004).…”
