A small earthquake centered near San Francisco rattled the area hours after a ceremony was held to mark the anniversary of the 1906 earthquake and fire that destroyed much of the city.
The U.S. Geological Survey says Monday's quake had a preliminary magnitude of 3.8 and struck about two miles southeast of Pacifica at 2:57 p.m. There were no immediate reports of damage or injuries.
Dozens gathered in San Francisco early Monday morning to remember the 105th anniversary of the 1906 earthquake, which killed thousands. There are only three known survivors of that quake, and only one of them _ Bill DelMonte, who was just a few months old at the time _ was able to make this year's commemoration.
