Los Angeles County — particularly the Pasadena and Alhambra areas — was rattled by an earthquake Sunday morning.
The preliminary 3.5-magnitude quake struck four kilometers south-southwest of South Pasadena just before 10 a.m., the USGS said.
The quake struck at a depth of 11.3 kilometers.
Seismologist Dr. Lucy Jones, who was in South Pasadena at the time, posted on X that the quake was “sharp and short.”
“The focal mechanism shows east-west thrust faulting, much like the 1987 Whittier Narrows quake,” Dr. Jones said. “[Sunday’s] quake is west of that event.”
According to KTLA Director of Content and Coverage Peter Wilgoren, the temblor felt like someone “took a tuning fork to the entire house.”
No injuries or damage were immediately reported.
