2. Hadith Allahs Messenger (peace be upon him) said, "When Allahcreated the Earth it began to oscillate, so He created themountains, ordered them onto it, and it became steady. Theangels marvelled at the strength of the mountains and askedtheir Lord whether there was anything in His creation strongerthan the mountains. God said, "Yes; iron is stronger thanmountains (rocks), for it breaks them." The angels said, "O Lord!Is there anything of Thy creation stronger than iron?" God said,"Yes; fire is stronger than iron, for it melts it." And the angelssaid, O Defender! Is there anything of Thy creation strongerthan fire?" God said, "Yes; water overcomes fire; it kills it andmakes it cold." Then the angels said, "O Lord! Is there anythingof Thy creation stronger than water?" God said, "Yes; windovercomes water: it agitates it and puts it in motion." They said,"O our Cherisher! Is there anything in Thy creation strongerthan wind?" God said, "Yes, the children of Adam, giving alms;that is, those who give with their right hands and conceal iffrom their left, they overcome all." 3. Disaster Monitoring Solutions 4.

Linked: Extreme Russian Fires and Pakistan Floods Two of the most destructive natural disasters of2010 were closely linked by a single meteorologicalevent, even though they occurred 1,500 miles(2,414 km) apart and were of completely differentnatures, a new NASA study suggests. The researchfinds that the same large-scale meteorologicalevent -- an abnormal Rossby wave -- sparkedextreme heat and persistent wildfires in Russia aswell as unusual downstream wind patterns thatshifted rainfall in the Indian monsoon region andfueled heavy flooding in Pakistan. http://www.youtube.com/watch?v=UroG2DS3xsg 7. Pakistan Floods 2010 8. Noreaster Floods - GOESSatellite This video of GOES satellite imagerywas created from data compiled March8 through 16, 2010. It shows floodingrains from a Noreaster that soakedthe U.S. Northeast. http://www.youtube.com/watch?v=CHIFVHhTZPA 9.

Landslide http://www.youtube.com/watch?v=kNrmczkpcPU&feature=related 11. Global Landslide Risks Reduce the loss of life from landslides Global, satellite-based early-warning system Landslide-prone regions, as shown in this image Coarse soil, land cover that was inadequate to stabilize the surface, and/or steep mountains The regions that have the highest risk of landslides are salmon pink Areas of moderate risk are lavender Regions with a slight risk are pale blue Areas where landslides occurred between 2003 and 2006 are marked with black dots on this map 12. Landslides-What they are & theircauses http://www.youtube.com/watch?v=JrV4uCVwmfk&feature=related 13. Landslide Evaluation 14. Landslide in Pakistan 15. ANALYSIS AND PREDICTION OF LANDSLIDESIN GIS (GEOGRAPHIC INFORMATION SYSTEMS) Mostlandslide potentialmodels determine terraininstability by combining slopemaps with soils data, thenselecting from the resultantsoil/slope categories thecombinations that are ratedfor severe erosion potential.Vegetativecoverconsiderations extend themodel. When available, mapsshowing historic landslidesites are added for bothestablishingand testinglandslide potential. 16. SHALSTAB Landslide Model SHALSTABlandslide potential model works best withdetailed elevation data. A Digital ElevationModel (DEM) spatial resolution of10 meters is desired.Raster-to- Vector procedures are used to convert base maps to project grid and raster-to-vector procedures are used to output a model. 17.
