NASA technology located four trapped Nepal earthquake victims by detecting their heartbeats

A technology developed by NASA and the US Department of Homeland Security designed to save people trapped by debris in natural disasters has been used in the field for the first time. FINDER (Finding Individuals for Disaster and Emergency Response) lived up to its name, locating and saving four people trapped under rubble for days after the 7.8 earthquake in Nepal killed more than 7,000 people and injured countless others.

FINDER is a radar machine that sends a continuous microwave signal through the rubble, and can detect a human’s breathing or heartbeat (and distinguish it from the movement of an animal). It can locate people hidden behind 20 feet of solid concrete or buried beneath 30 feet of rubble, and the person doesn’t need to be conscious to be detected.

The technology is based on remote radar sensing that NASA originally developed to detect life on other planets. It was deployed with search and rescue teams to Nepal on April 29, four days after the earthquake struck. It had been tested many times before, but had yet to be implemented in a real-life emergency.

NASA is working to commercialize the FINDER technology in order to get it into the hands of more first responders. No doubt more earthquake victims could have been saved if FINDER was deployed with more search and rescue teams.
