It was a small earthquake, but it probably felt stronger to the people who felt the shaking because it was centered close to Fontana.
Eyewitness News received several calls from residents of San Bernardino, Fontana, Bloomington, Hesperia and Rancho Cucamonga, who woke up because of the quake. The U.S. Geological Survey said the quake was centered about 4 miles northwest of Fontana.
At 8:18 a.m., the area was hit with a 2.6-magnitude earthquake, and a third earthquake hit at 8:30 a.m., a 2.6-magnitude.
There are no reports of damage or injury.
The last time there was any significant in the local area was March in Chino Hills, which was a 3.1-magnitude quake.
Earlier this week, there were a series of quakes in the gulf of California.
