**2.8 Microwave radar**

NASA's FINDER technology was used to detect any human heartbeats trapped under debris, which uses microwave radar sensors to remotely detect heartbeats and respiration in order to find survivors in the rubble [26]. Shortly after the earthquake, the technology was transported to the disaster area. It was developed at NASA's Jet Propulsion Laboratory in California and was also used following the 2010 Haiti earthquake. Its ability to distinguish between human and machine motion - and even between humans and animals - proved critical in the chaotic and urgent environment of search and rescue [27, 28]. Its prototypes were built inside a medium-sized Pelican case, which was tough enough to transport the equipment during natural disasters [29].
