Scientists have developed a smartphone app that can be used in emergency situations  arising due to earthquakes, floods or forest fires, where mobile phone infrastructure is  often rendered useless. The system created by researchers at the Universidad de Alicante (UA) in Spain makes  it possible to locate people who have suffered an accident in remote locations without  a phone signal and where a speedy rescue is essential to save lives.
