The quake, which initially registered as 4.7, hit at 12:20 p.m. local time (3:20 p.m. ET) and was centered about 2.5 miles southeast of Highland Park in northeastern Los Angeles.
The U.S. Geological Survey has revised the magnitude of the earthquake to 4.4.
The Los Angeles Police Department reported feeling the earthquake and advised the public to use 911 only for emergencies and be prepared for aftershocks.
An hour later, the Los Angeles Fire Department stated that their inspections revealed no major damage or injuries within the city.
In nearby Pasadena, the quake caused a water pipe to burst inside City Hall, leading to a temporary evacuation of employees, but no significant damage was reported.
The tremor was also felt as far as Hollywood, about 9 miles west of South Pasadena, where it created noticeable rattling and a rocking sensation in buildings.
Seismologist Lucy Jones from the California Institute of Technology noted that the earthquake likely occurred on a shallow fault, similar to the 1987 Whittier Narrows quake, which was a magnitude-5.9 event that resulted in eight deaths and extensive property damage.
