A 6.0 magnitude earthquake is enough to jolt most people awake -- and here's proof.



Jawbone, the maker of a fitness tracking bracelet, analyzed data from its tech savvy users to create an infographic showing how the earthquake impacted sleep patterns.



The earthquake's epicenter was located about 6 miles south-southwest of Napa, California, and 51 miles west-southwest of the state capital, Sacramento.

Jawbone looked at data from cities that are less than 15 miles from the epicenter and found that 93 percent of users in those cities woke up abruptly when the quake struck at 3:20 a.m.



Not surprisingly, many residents took a while to drift back to sleep, while 45 percent of wearers less than 15 miles from the epicenter opted to stay awake for the rest of the night.



The earthquake was so strong that 55 percent of wearers in San Francisco and Oakland, even farther from the epicenter, were woken up by the vibrations.



It was the largest one to shake the Bay Area since the 1989 6.9-magnitude Loma Prieta Earthquake.
