LOS ANGELES, May 3 (UPI) -- Los Angeles experienced a mild 3.8 earthquake Sunday morning, according to the U.S. Geological Survey.
The quake was barely noticeable for many residents of the city, and it occurred at 4:07 a.m. It originated 5.6 miles under ground. No damage has been reported.
The epicenter of the quake was near Los Angeles International Airport.
According to the Los Angeles Times, many people on Twitter questioned if the quake resulted from hydraulic fracturing, or "fracking," which has been known to cause earthquakes.
However, Caltech's Lucy Jones claimed on Twitter that is unlikely, since the quake originated from too deep underground.
