SACRAMENTO COUNTY, Calif. (KGO) -- A 2.9 magnitude struck near Isleton, California in Sacramento County Monday morning, according to the U.S. Geological Survey, less than a week after a 4.2 quake hit the same area.

The quake hit at around 7:42 a.m. It had a depth of 8 km, the USGS said.

It was originally reported as a 4.0 but then downgraded to 2.9.

There is no word of any injuries or damage.

The quake that struck Isleton last week set off a ShakeAlert to Northern Californians because it was initially estimated as above a 5.0, but then later downgraded minutes later.
