A series of small earthquakes occurred in Ontario on Saturday morning, as reported by the U.S. Geological Survey.
The initial quake, measuring 3.5 in magnitude, struck at approximately 10:05 a.m., with its epicenter located about three miles southeast of Ontario. This was followed by a stronger quake at 10:34 a.m., which registered 3.9 in magnitude and was centered east-southeast of Ontario. An aftershock of 2.6 magnitude was reported later at 11:45 a.m., about two miles southeast of the area. Throughout the day, several minor quakes, ranging from magnitudes 1 to 2, were also recorded.
Local residents expressed their shock at the tremors. Lucy Campa, a store clerk, described the event as feeling like a truck was crashing into the store due to the intensity of the shaking. Ontario resident Gaby Galdamez noted that the second tremor was more pronounced, causing everyone to momentarily freeze in place.
Fortunately, there were no immediate reports of significant damage resulting from the quakes. Residents across Ontario, Fontana, San Bernardino, Riverside, Pomona, and Chino reported feeling the shaking.
Seismologist Dr. Lucy Jones commented on the situation, stating that the region is currently experiencing a small swarm of seismic activity along the Fontana Seismicity Lineation, an area known for a series of minor earthquakes.
