In the heart of the night, residents of Ontario, California, were jolted awake by a 3.8 magnitude earthquake, serving as a reminder that seismic activity is not exclusive to the western United States. The quake, which occurred approximately 20 minutes before midnight, was centered just a few miles outside of Ontario, according to the U.S. Geological Survey (USGS). Despite its moderate magnitude, the tremor was felt across Southern California, with reports reaching as far south as Oceanside and Escondido.
This recent earthquake comes on the heels of a series of seismic events in the region. Just days before, nearly 20 earthquakes rattled parts of Southern California, beginning with a 4.8 magnitude quake near El Centro on February 11. The epicenter of the latest 3.8 magnitude earthquake was reported to be around 2 miles southeast of Ontario in San Bernardino County, near the Ontario International Airport. Fortunately, there were no immediate reports of damage or injuries.
The USGS emphasizes that the potential for damage depends on various factors, such as the distance from the earthquake, soil type, building construction, and other variables. While the recent 3.8 magnitude earthquake did not result in significant damage or impact, it underscores the importance of earthquake preparedness in the region.
One noteworthy aspect of the recent seismic activity is the shallow depth of the earthquakes. The 3.8 magnitude quake had a depth of approximately 7.4 miles, while a moderate magnitude 3.6 earthquake that occurred on Thursday, February 15, had an even shallower depth of 13 km (8 mi). The shallowness of these quakes contributed to a more pronounced effect near the epicenter, intensifying the shaking experienced by residents.
Residents in different parts of the affected areas reported varied experiences. In the eastern portion of the Victor Valley, some described the earthquake as a “mild shake,” while those in the Ontario area reported a “strong jolt” that rattled their homes. These personal accounts highlight the subjective nature of earthquake experiences and the importance of being prepared for unexpected seismic events.
In the past 24 hours, Ontario has experienced additional seismic activity, including a light magnitude 2.4 earthquake near Malibu. The USGS provides continuous monitoring of seismic events, tracking their magnitude, depth, and location. This ongoing monitoring helps assess the seismic landscape and provides valuable data for scientists and emergency response teams.
The recent earthquake in Ontario, California, serves as a poignant reminder of the unpredictable nature of seismic activity in the region. While the 3.8 magnitude quake did not cause significant damage, its occurrence, coupled with the recent series of earthquakes, raises concerns about earthquake preparedness. Residents are encouraged to stay informed, be prepared, and follow safety guidelines to mitigate the impact of future seismic events in the area.
