Would not it be nice to be notified before a major natural disaster is about to hit? Well, Apple is set to do just that, and the IOS feature 5 "Earthquake Alarm" notice, which is intended for users in Japan. When the 8.9/9.0 magnitude earthquake that hit Japan in March, when the power failure, fire, and very damaging tsunami in Japan, the iPhone could certainly use the built-in earthquake alarm, especially when it is a of the most earthquake-prone countries in the country.
But it seems that something has been in use in Japan since 2007. Japan's three largest mobile operators, NTT DoCoMo, KDDI and Softbank Mobile, all developed a system of mass communication that sends alerts to multiple users simultaneously. Earthquake Early Warning (EEW), which Time Magazine called "the most advanced in the world", is issued to the general public when the system detects vibration and then calculates the epicenter of an earthquake is. Feature phones have received these warnings since 2007, and 3G phones on the market after 2007 are required to have this service. However, foreign manufacturers like Nokia, Apple, HTC, LG and Samsung does not support it.
EEV system is important because it can provide a range of seconds for a few minutes warning before the earthquake actually strikes. You can enable or disable message notification of the panel setting, the iPhone iPhone in Japan. It 'been previously downloaded apps, but the inclusion of the term IOS means rather than relying on third-party software and deploy as soon as you connect the iPhone to the default
It would be nice to see this statement as part of the IOS system around the world, not only in Japan but we are happy to get them from Apple. However, we wonder if the continuous connection with the battery life UNION influence on your mobile phone? Personally, I prefer my phone to download a little 'more often, and do not know when the earthquake hit as there is no alternative at all.
