An earthquake struck Julian Monday morning, resonating across San Diego County, with reports of shaking extending to parts of Los Angeles and Tijuana.
According to the United States Geological Survey, a 5.2-magnitude earthquake was recorded around 10 a.m., located 5 kilometers, or 3.1 miles, just south of Julian, with a depth of 8 miles.
In the wake of the quake, the USGS reported more than a half dozen small aftershocks with magnitudes of 2.5 or more.
The Scripps Institution of Oceanography provided a seismic wavefield animation of the earthquake.
This earthquake follows a 3.5-magnitude temblor in the same area that occurred Sunday afternoon.
The National Weather Service confirmed that no tsunami was expected following the tremor.
Shaking was felt as far north as Escondido and east to Mexicali, according to entries on the USGS’s ‘Did you feel it?’ website.
Local news outlets, including NBC Los Angeles, reported some shaking in northern neighborhoods.
At the NBC 7 building in Kearny Mesa, the quake prompted noticeable tremors, with reporter Joe Little observing construction crews evacuating their worksite amidst the earthquake alert.
Nicole Gomez, another reporter stationed at the Registrar of Voters office in Kearny Mesa, described how her vehicle shook vigorously as many car alarms erupted inside the parking garage.
According to experts, the fault responsible for Monday’s earthquake is the well-known Elsinore Fault.
“After the earthquake, we’re going to have smaller and smaller earthquakes occur, and this tail can last for days, weeks, sometimes even months. For very large earthquakes, that can last years,” Dr. Rafael Almeida, an assistant professor at San Diego State University, told NBC 7.
Despite the significant quake, no damage was reported in the county.
Nonetheless, several transportation services, including the Metropolitan Transit Service, COASTER, Breeze, and the Pacific Surfliner, experienced disruptions for the remainder of the day.
The earthquake did result in a small rockslide on State Route 76, east of E Grade Road.
NBC 7 spoke with workers downtown about their reactions, which varied from surprise to calm acceptance, as some reported, “just another day in the office,” although shaken nonetheless.
“Being a native Californian, I haven’t felt one this large in a while, but it was not scary or anything like that,” reflected Sandy Prince, who was present downtown during the quake.
Alice Dufresn, a worker who usually doesn’t work on Mondays, had come in to train Sandy and found herself in the office during the earthquake.
“They pulled me out of retirement,” Dufresn noted humorously.
Ashley Pinnick, witnessing the quake’s effects on her family, described it as a sound and feel unlike anything she’d experienced before.
“It sounds like a rumbling in the Earth. It sounds like the Earth is upset. That’s what it sounds like,” Pinnick remarked.
A security camera captured her instinctive reaction as her Ramona home shook; she quickly grabbed her 9-month-old son, Michael, and rushed out the front door.
Upon further inspection, broken ceiling plaster was falling, leading her to believe the ceiling might collapse.
Although the shaking lasted what felt like longer, it was only about 30 seconds, and fortunately, the ceiling remained intact, albeit not without damage.
