(CNN) -- A 5.4-magnitude earthquake rattled southern California Wednesday, the U.S. Geological Survey said. The temblor, centered about 60 miles northeast of San Diego, was first reported by USGS to be at 5.7 magnitude but the agency later downgraded it to 5.4.
There were no immediate reports of damages or injuries.
The city closest to the quake was Borrego Springs, located in San Diego County.
"(There was) no damage no injures whatsoever," San Diego County Fire Department spokesman Maurice Luque told CNN. "Not even a spike in call volume at our 911 center which normally happens when we have a quake of this magnitude."
Neighboring Riverside County also reported no major incidents as a result of the quake.
"So far in Riverside County we have had no significant damage reports either from our fire stations of from the citizens in the county," Riverside Fire Capt. Jeremy Snyder told CNN.
In Palm Springs, businesses reported feeling the quake, but suffered no damage. Palm Springs was about 28 miles from the epicenter of the quake.
An employee at Le Parker Meridian Hotel in Palm Springs described the quake as a "pretty big jolt."
At Jensen's Finest Food in Palm Springs, manager Tom Hodges said he had maybe 20 items fall off the shelves, but not a single broken glass.
