The USGS says the first quake, a magnitude 3.2, was centered east of Highway 242 in Concord and struck at about 7:01 a.m. PDT Wednesday. The second and largest, a 3.6-magnitude, struck at 7:32 a.m. It was later downgraded to a 3.5. The third, a 2.6-magnitude, hit shortly after at 7:35 a.m.
Over 100 people, mostly in Pleasant Hill, reported feeling the earthquakes, according to USGS' online "Did You Feel It" survey.
People chimed in over Twitter after some light shaking.
