iOS 5 will include functionality specific to the land of the rising sun to warn the Japanese of a possible earthquake.
Japan is still very marked by the terrible earthquake which shook the country last March 11 and which subsequently caused a devastating tsunami.
Apple seems to want to help, in a way, this country located in a zone of very important seismic faults. This notification system should occur, in the worst case, a few seconds before the earthquake and in the best case, 1 to 2 minutes before. This feature is linked to the Japanese national earthquake detection system using 1000 seismographs spread across the country.
Apple warns that using this notification system will reduce the life of the iPhone.
