3:20 a.m.: The time the earthquake rattled residents awake across the region.

10-20 seconds: The length of the earthquake, which hit about six miles south of Napa, according to the United States Geological Survey.

208:  The number of patients treated or admitted at Napa's Queen of the Valley Medical Center, according to a representative. Of those, 17 were admitted and one person there is in critical condition. Another 13-year-old boy was taken in serious condition to UC Davis Medical Center. St. Helena Hospital reported treating eight people as of 6 p.m. Sunday.

50: Number of fires the Napa Fire Department put out.

90-100: The total number of homes and buildings rendered uninhabitable by the earthquake, the director of California Governor's Office of Emergency Services said, according to The Associated Press.
