Fitness tracker allowed to determine the epicenter of the earthquake
Fitness trackers, such as Jawbone UP24, allow you to find out a lot about the behavior of their owners. And the earnings of a manufacturing company may depend not only on the sale of the bracelets themselves, but also on consumer research: for example, recent analysis of sleep tracking statistics helped to understand what time people sleep in big cities, how waking time depends on the availability of the metro and how much activity increases at the weekend.
As it turned out, this is not the only use for the bracelet. On the company's website today there was information that the epicenter of the largest earthquake in 25 years in Northern California could be determined from data from a variety of fitness trackers.
The company's specialists examined how the earthquake affected UP users by analyzing their sleep statistics.

Napa County and the cities of Sonoma, Vallejo and Fairfield were less than 15 miles from the epicenter. About 93% of UP users in these cities woke up sharply at 3:20 am - just at the beginning of an earthquake. The farther from the epicenter, the more people continued to sleep, despite the tremors. In San Francisco and Oakland, for example, only 55% woke up. In Santa Cruz and Modesto (from 75 to 100 miles from the epicenter), much less people woke up at night.
It was difficult for the awakened ones to return to bed - this is how 45% of bracelet owners did not fall asleep at all more that night.
