Think you could sleep through an earthquake? Probably not, judging by data from Jawbone. The company says that almost everyone using its Jawbone Up device to track their sleep near South Napa was awakened by yesterday's earthquake. About 90 percent of its users were asleep, and the closer you were to the epicenter, the more likely it is you woke up. Farther out, about half the users in San Francisco and Oakland arose; almost nobody was disturbed 75 to 100 miles away in Modesto. Since Jawbone's fitness trackers push data to smartphones and other devices, the company was able to get a quick and detailed look into how the locals felt. The stats are interesting, to be sure, but may give you pause if didn't realize Jawbone could publish your exercise stats at a moment's notice.
