In New Zealand, Christchurch, rescue workers are employing modern technology to track down survivors under the rubble. The earthquake had taken multiple lives and many more are still buried.
Traditionally, rescue workers carefully combs the area for clues and listen for cries from the survivor. With cell phone triangulation, rescue workers can prioritize and increase the efficiency in their search for survivors. Cell phone triangulation works by calculating the distance between the towers to your cellphone, and the phone does not even have to GPS enabled.
This does raise some questions though, like is this an infringement of privacy rights? and what modern phone have the power to stay on after 48 hours with 3G enabled and maybe WIFI turned on?
