The iPhone users won't receive the alerts through Apple's operating system，but they can download the MyShake app. Also，the company announced that Android phones would begin detecting earthquakes from around the world through their motion­sensing accelerometers. “Your Android phone can be a mini­seismometer，joining millions of other Android phones out there to form the world's largest earthquake detection network，”according to a blog post of the company. More than 2 billion devices run the Android operating system. Hundreds of millions of people live in earthquake­prone areas. But
