This is a graph that Jawbone released from yesterday earthquake in Napa, Northern California.  Pretty cool, when you have access to data of thousands of users and you can correlate them with external factors. On the other side this is what everyone expects when you deal with customer data. You sell a thing to someone to help them doing something, but in return you get valuable data from them. It’s the Big Data of things, and you’re the product. For good and bad.
