RIDGECREST, California - A magnitude 4.9 aftershock of last week's Southern California powerful earthquakes was felt widely Friday morning in the region.
The U.S. Geological Survey said the quake occurred at 6:11 a.m. and was centered about 5 miles northeast of the Mojave Desert city of Ridgecrest, which is home to 28,000 people.
The quake was felt very lightly in the Los Angeles area.
There have been thousands of aftershocks of the magnitude 6.4 earthquake on July 4 and the 7.1 quake that occurred the next day.
The aftershocks have been dying off but are expected to continue for some time.
Seismologist Lucy Jones said that the 4.9 quake is normal and is having its own aftershocks.
The USGS said the probability of a 7.1 or larger quake has fallen to less than 1%.
