A 6.0 magnitude earthquake Sunday morning in Northern California was the largest quake to hit the Bay Area in almost 25 years, according to the U.S. Geological Service.
The newspaper also reported some streetlights were knocked out and crews responded to scattered fires.
CNN is also reporting people are trapped.
The quake was approximately 6.7 miles deep, USGS said, adding that the probability of a strong and possibly damaging aftershock in the next seven days is approximately 54 percent. As many as 70 small aftershocks are likely in the next week.
The USGS tweeted that the quake was the strongest in the area since the Loma Prieta earthquake in 1989.
The Browns Valley section of the West Napa fault is suspected, although no exact determination has been made, the USGS added.
USGS is asking anyone who felt the earthquake to share their experiences, saying the information will help them greatly.
