Distributed Sensors

Yet another use for the tricorders everyone carries around these days:

"The University of California-Berkeley, along with funding from the state of California, built an app called "MyShake" and a cheap, effective earthquake detection network was born, at least, it was born for people who installed the app.

What if you didn't need to install the app? What if earthquake detection was just built in to the operating system? That's the question Google is going to answer, with today's announcement of the "Android Earthquake Alerts System." Google is going to build what it calls "the world’s largest earthquake detection network" by rolling earthquake detection out to nearly every Google Play Android phone."
