There are 17 rare earth metals in the world, and 16 of them are used in mobile phones. The mining of these minerals, through the injection of high-pressure wastewater, puts existing earthquake faults under more pressure, and ultimately causes more earthquakes. The largest one linked to mining activities happened in Siberia in 2013, registering 6.1.
