It was NASA’s FINDER that found the four individuals who were trapped in the debris. The device is designed to track a human heartbeat and is able to sense through 30 feet of debris.
The device is just one of NASA’s tools that was just recently developed and had successfully found four individuals. NASA’s FINDER or Finding Individuals for Disaster and Emergency with its microwave radar is intended to thoroughly scan for human heartbeats.
The first invented sample of the device was made by NASA together with the U.S. Department of Homeland Security’s Science and Technology Directorate. The device is just almost the size of a suitcase yet it is quick to respond to any signals of a heartbeat even through 30 feet of debris or 20 feet through concrete. It could also readily catch a signal at a distance of 100 feet in an open air. The device can also identify a human heartbeat from an animal which can help rescuers concentrate on trapped people to get rescued first than household pets which may also be around the area.
The Nepal tragedy has seen the latest of modern technology created to help disaster management and response as NASA provides its satellites to indicate maps of areas that were greatly affected, while DigitalGlobe opened its satellite imagery of the damaged areas for free so that response and recovery teams are able to thoroughly see the area from above while they suggest information to specific areas during their operation.
Some companies like Skycatch have aerial drones to provide high-resolution 2D and 3D images for free so that government workers and voluntary groups are able to determine the degree of damage in an area.
