The problem IIDENTIFICATION OF VOIDS IN EARTHQUAKE solves

"After natural and man-made disasters victims may survive in voids that are formed naturally in collapsed structures. In a pancake collapse scenario of a multi storied building, especially in a mega earthquake scenario in a metropolitan city, these voids may have survivors. Due to the complex and unstructured occlusions in disaster areas, visual and manual search is time consuming and error prone. There is a requirement to evolve a system which can automatically detect, locate, and characterize voids buried in disaster rubble using ground penetrating radar (GPR).Presently NDRF holds Life Detector type I and II, which work on seismic sensors, which can detect the smallest vibration to locate live victims. Due to concentration of huge crowds in nearby areas of the disaster site, these instruments give false alarms. In a complex and unstructured occlusions usage of Ground Penetrating radar (GPR) can give more accurate data and would be able to detect, locate and help voids. a) The First responders will be able to identify and locate the critical voids for rapid search and rescue operations with the help of Ground Penetrating Radar. b) Due to the complex and unstructured occlusions in disaster areas, visual and manual search is time consuming and error-prone, the radar system will automatically detect, locate, and characterize voids buried in disaster rubble."
