A magnitude-4.4 earthquake struck Highland Park, Southern California, on Monday afternoon, causing noticeable shaking in the area around 12:20 p.m.
Following the quake, incidents related to the earthquake were reported in Pasadena, where one person became trapped in an elevator and a water pipe burst in front of city hall, according to Lisa Derderian, the city’s public information officer. “The quake was felt strong in Pasadena here,” she mentioned, noting that it coincided with the first day of school for the Pasadena Unified School District. “We hope teachers and school staff are discussing what to do and preparing for aftershocks.”
The Los Angeles Fire Department activated its earthquake response protocols, deploying fire crews from all stations to assess any potential damage. Fortunately, no major issues were discovered.
The shaking was reported across the Los Angeles area and into northern Orange County, as stated by Robert De Groot from the U.S. Geological Survey, who also noted that ShakeAlert early warning messages were issued. Initially, the quake was reported with a magnitude of 4.7 and at a depth of 9 kilometers.
At least two aftershocks, measuring around 2.1 in intensity, were felt in the vicinity, as reported by NBC4 Meteorologist David Biggar. Residents in the East Los Angeles neighborhood of El Sereno also experienced significant shaking. “It was like a hit, like a hard jolt,” said El Sereno resident Lorrie Munoz. “I honestly thought our wall was going to fall over.”
The Los Angeles Police Department advised residents to prepare for aftershocks, reminding the public to use 911 only for emergencies.
In response to the quake, which was felt as far south as San Diego, experts emphasized the importance of emergency preparedness. Jeff Edelstein, owner of SOS Survival Products, recommended that people keep essential items in their emergency kits. “Water; at least a three-day to two-week supply of water, food—whether it’s canned food or food bars—some first aid supplies, and lighting essentials like flashlights, lanterns, and batteries,” he suggested.
Edelstein also highlighted the importance of having updated emergency kits, referencing an “under-the-bed kit” inspired by the 1994 Northridge earthquake, which injured many when they attempted to flee through their homes amidst the chaos.
